| ○ | ○ | Article | Lucy With Agents in the Sky: Trustworthiness of Cloud Storage for Industrial Internet of Things | The industrial Internet of Things (IIoT) has the potential to transform several industries. However, reliable data collection, processing, and analytics cannot be performed if the underlying cloud storage is not trustworthy. The current IIoT architectures tend to adopt cloud computing as a backbone for their implementation and further deployment. Therefore, the trustworthiness of the cloud storage is of paramount importance for the design of efficient and reliable IIoT. This becomes very challenging if the data storage is outsourced to a third party, which may raise many problems such as noncompliance to service-level agreement, data theft, and privacy issues. Mobile agents have a number of characteristics including mobility, lightweight, autonomous, reactive, and intelligent making them ideal for deployment in many distributed applications. Therefore, in this article, we propose a multiagent-based approach to address the geolocation assurance problem of the outsourced data in the context of IIoT. As a result, we achieve efficient geolocation assurance with manageable costs without the need of a trusted third party. | Khan, Abid; Din, Sadia; Jeon, Gwanggil; Piccialli, Francesco | Aberystwyth Univ, Dept Comp Sci, Aberystwyth SY23 3DB, Dyfed, Wales; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Xidian Univ, Sch Elect Engn, Xian 710071, Peoples R China; Incheon Natl Univ, Dept Embedded Syst Engn, Incheon 442709, South Korea; Univ Naples Federico II, I-80138 Naples, Italy | Khan, Abid/V-1488-2019; Piccialli, Francesco/ABC-2457-2020; Din, Sadia/ADU-4679-2022 | 55209201300; 57188997144; 15022497800; 42762051900 | abk15@aber.ac.uk;saadia.deen@gmail.com;gjeon@gmail.com;francesco.piccialli@unina.it; | IEEE TRANSACTIONS ON INDUSTRIAL INFORMATICS | IEEE T IND INFORM | 1551-3203 | 1941-0050 | 17 | 2 | SCIE | AUTOMATION & CONTROL SYSTEMS;COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS;ENGINEERING, INDUSTRIAL | 2021 | 11.648 | 3.0 | 0.53 | 2025-07-30 | 7 | 10 | Geology; Cloud computing; Internet of Things; Protocols; Informatics; Servers; Logic gates; Cloud computing; Internet of Things (IoT); industrial Internet of Things (IIOT); multiagents | TAXONOMY | Cloud computing; industrial Internet of Things (IIOT); Internet of Things (IoT); multiagents | Autonomous agents; Digital storage; Mobile agents; Privacy by design; Storage as a service (STaaS); Trusted computing; Cloud storages; Distributed applications; Multi-agent based approach; Outsourced datum; Reliable data collections; Service Level Agreements; Third parties; Trusted third parties; Industrial internet of things (IIoT) | English | 2021 | 2021-02 | 10.1109/tii.2020.2974493 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Progress in organic semiconducting materials with high thermal stability for organic light-emitting devices | Organic light-emitting devices (OLEDs) have been extensively studied over the past three decades and are still attracting attention owing to their potential use in flexible and foldable displays. To achieve highly durable OLED displays for flexible devices, constitutive OLED materials need to be stable in various environments, including those with thermally and mechanically severe conditions. To this end, the present review aims to investigate the progress of OLED material research over the past two decades with respect to thermal stability. The literature survey is first conducted using the keyword "OLEDs" and then narrowed down to "high thermal stability materials for OLEDs." The number of search results indicates that creating OLED materials with high thermal stability is a widely studied topic in the field of OLED research and has undergone an average growth rate of approximately 15% per year over the past two decades. In this review, the OLED materials used as core layers (ie, the hole injection and transport layers, emission layers, and electron injection and transport layers) are thoroughly analyzed, and the best representative materials are discussed in detail by summarizing their major thermal and electronic characteristics. Finally, several previous reports on flexible and foldable OLED displays are analyzed to determine the importance of the stability of their constitutive materials. | Lee, Sooyong; Kim, Hwajeong; Kim, Youngkyoo | Kyungpook Natl Univ, Dept Chem Engn, Sch Appl Chem Engn, Organ Nanoelect Lab, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Chem Engn, Sch Appl Chem Engn, KNU Inst Nanophoton Applicat KINPA, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Environm Sci & Technol, Daegu, South Korea | 55421486100; 15520531700; 10340424400 | ykimm@knu.ac.kr; | INFOMAT | INFOMAT | 2567-3165 | 3 | 1 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2021 | 24.798 | 3.0 | 3.31 | 2025-07-30 | 48 | 49 | durability; flexible; foldable; glass transition temperature; OLED; thermal stability | HOLE-TRANSPORTING MATERIALS; BIPOLAR HOST MATERIALS; POLY-SI TFTS; TRIPLET ENERGY; PIXEL CIRCUIT; CELLULOSE NANOCOMPOSITE; PHOSPHORESCENT OLEDS; EFFICIENT BLUE; DIODE; GREEN | English | 2021 | 2021-01 | 10.1002/inf2.12123 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | A novel pathway for initial biotransformation of dinitroaniline herbicide butralin from a newly isolated bacterium Sphingopyxis sp. strain HMH | Butralin (N -secButyl-4-tert-butyl-2,6-dinitroaniline) is a highly persistent dinitroaniline herbicide frequently detected in the environment. In this study, butralin-degrading soil bacterium, Sphingopyxis sp. strain HMH was isolated from agricultural soil samples. Based on whole genome sequence analysis of the strain HMH, the gene encoding a nitroreductase NfnB was identified and expressed in Escherichia coli (E. coli), and protein was purified to homogeneity. NfnB is a flavin-nitroreductase, found to be a functional tetramer, composed of subunit mo-lecular mass of 25 kDa. The metabolites from butralin degradation by strain HMH and purified NfnB were identified using ultra performance liquid chromatography high resolution mass spectrometry (UPLC-HRMS), and a novel mechanism of butralin degradation was proposed. NfnB selectively nitro-reduced butralin into N (sec Butyl)-4-(tert-butyl)-6-nitrobenzene1,2-diamine, followed by formation of 5-(tert-Butyl)-3 -nitrobenzene-1,2-diamine and butanone by Ndealkylation through possible hydroxylation reaction onto the carbon linked amine of the N-(sec-Butyl) moiety. In our study, we could not detect the hydroxylated product 2-(2-Amino-4-tert-butyl 6-nitrophenylamino)-butan-2-ol) (carbinolamine), instead its Schiff base product (E)-2-(Butan-2-yildenea mino)-5(tert-butyl)-3-nitroaniline was detected. The release of butanone was further confirmed by derivatization with 2,4dinitrophenylhydrazine (DNPH) followed by MS analysis. In conclusion, this study explores a novel multi-functional flavinnitroreductase family enzyme NfnB, catalyzing unique and sequential nitror-eduction and N-dealkylation through oxidative hydroxylation of dinitroaniline herbicide butralin. | Ghatge, Sunil; Yang, Youri; Moon, Seonyun; Song, Woo-Young; Kim, Tae-Young; Liu, Kwang- Hyeon; Hur, Hor-Gil | Gwangju Inst Sci & Technol GIST, Sch Earth Sci & Environm Engn, Gwangju 61005, South Korea; Kyungpook Natl Univ, Coll Pharm, BK21 Plus KNU Multiom Based Creat Drug Res Team, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu 41566, South Korea | Ghatge, Sunil/AAH-3946-2020 | 57208530238; 57201256624; 57218292356; 57201261557; 57049826900; 55768214700; 58530093100 | hghur@gist.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 402 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 0.98 | 2025-07-30 | 24 | 25 | Butralin; Biotransformation; Flavin-nitroreductase; N-dealkylation; Sphingopyxis | REDUCTIVE METABOLISM; ESCHERICHIA-COLI; BIODEGRADATION; PENDIMETHALIN; DEGRADATION; NITROREDUCTASE; TRIFLURALIN; OXYGEN; PERSISTENCE | Biotransformation; Butralin; Flavin-nitroreductase; N-dealkylation; Sphingopyxis | Aniline Compounds; Biotransformation; Escherichia coli; Herbicides; Sphingomonadaceae; Bacteria (microorganisms); Escherichia coli; Sphingopyxis; Agricultural robots; Escherichia coli; Gene encoding; Herbicides; Ketones; Liquid chromatography; Mass spectrometry; Metabolites; Nitrobenzene; Purification; Weed control; 2 butanone; 2,4 dinitrophenylhydrazine; aniline derivative; bacterial RNA; butralin; carbinolamine; herbicide; nitro derivative; nitrobenzene derivative; nitroreductase; RNA 16S; Schiff base; tetramer; unclassified drug; aniline derivative; butralin; 2 ,4- dinitrophenylhydrazine; Agricultural soils; Derivatizations; Escherichia coli (E. coli); Hydroxylation reactions; Multi-functional; Ultra performance liquid chromatography; Whole genome sequences; agricultural soil; bacterium; biotransformation; gene expression; genetic analysis; genome; homogeneity; liquid chromatography; metabolite; amino acid sequence; Article; bacterial gene; bacterial strain; bacterium identification; bacterium isolation; biotransformation; controlled study; dealkylation; degradation; derivatization; Escherichia coli; heterologous expression; hydroxylation; mass spectrometry; metabolite; molecular cloning; molecular weight; nfnb gene; nonhuman; nucleotide sequence; organisms by carbon source; phylogenetic tree; protein expression; protein purification; RNA sequence; rute gene; Shingopyxis granuli; soil microflora; ultra performance liquid chromatography; whole cell; whole genome sequencing; ydja gene; biotransformation; genetics; Sphingomonadaceae; Hydroxylation | English | 2021 | 2021-01-15 | 10.1016/j.jhazmat.2020.123510 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Adsorptive removal of hazardous organics from water and fuel with functionalized metal-organic frameworks: Contribution of functional groups | The purification of contaminated water and fuel is very important for our sustainability. Adsorptive removal has attracted significant attention because of possible applications in industry and the rapid development of metal organic frameworks (MOFs), which can be competitive adsorbents. In this review, the possible/competitive purification of water (contaminated with organics) and fuel (composed of Sand N-Containing compounds) via adsorption using MOFs, especially those with various functional groups (FGs), will be discussed. The contribution of FGs such as-OH,-COOH,-SO3H,-NH2, and-NH3+ to adsorption/purification will be analyzed in detail, not only to understand the plausible adsorption mechanism but also to utilize specific FGs in adsorption. Moreover, methods for introducing FGs onto MOFs will be summarized. Finally, the prospects for both adsorption/removal and emerging fields will be suggested. Studies for practical applications in industry with shaped MOFs from inexpensive route will be important. The solution pH should be considered for the adsorption of aqueous solution. Applications of MOFs in other fields like storage/delivery and enrichment of analytes might be deeply studied. | Yoo, Dong Kyu; Bhadra, Biswa Nath; Jhung, Sung Hwa | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Bhadra, Biswa/ABG-6935-2021; Bhadra, Biswa Nath/ABG-6935-2021; Jhung, Sung/AAO-6683-2021 | 57201339246; 56982844300; 6701659467 | sung@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 403 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 2.41 | 2025-07-30 | 153 | 155 | Adsorption; Fuel; Functional groups; Mechanisms; Metal-organic frameworks; Removal; Water | NITROGEN-CONTAINING COMPOUNDS; LIQUID-PHASE ADSORPTION; ACID-BASE INTERACTIONS; P-ARSANILIC ACID; MODEL FUEL; REMARKABLE ADSORBENT; ENHANCED ADSORPTION; AQUEOUS-SOLUTION; MALACHITE GREEN; NITROIMIDAZOLE ANTIBIOTICS | Adsorption; Fuel; Functional groups; Mechanisms; Metal-organic frameworks; Removal; Water | Adsorption; Ammonia; Fuel purification; Fuels; Metal-Organic Frameworks; Organometallics; Water pollution; acid; amino acid; base; carboxylic acid; cation; fuel; hydroxyl group; metal organic framework; sulfonic acid derivative; water; Adsorption mechanism; Adsorptive removal; Contaminated water; Functionalized; Hazardous organics; Metalorganic frameworks (MOFs); Purification of water; Solution pH; adsorption; aqueous solution; chemical compound; detection method; organic pollutant; pollutant removal; purification; water treatment; adsorption; aqueous solution; chemical interaction; chemical modification; hydrogen bond; pH; protonation and deprotonation; purification; Review; static electricity; water management; Chemicals removal (water treatment) | English | 2021 | 2021-02-05 | 10.1016/j.jhazmat.2020.123655 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Bio-electrokinetic remediation of crude oil contaminated soil enhanced by bacterial biosurfactant | The present study evaluating the coupling between bioremediation (BIO) and electrokinetic (EK) remediation of crude oil hydrocarbon by using bio-electrokinetic (BIO-EK) technique. The application of bacterial biosurfactant (BS) may increase the remediation efficiency by increasing the solubility of organic materials. In this work, the potential biosurfactant producing marine bacteria were isolated and identified by 16S rDNA analysis namely Bacillus subtilis AS2, Bacillus licheniformis AS3 and Bacillus velezensis AS4. Biodegradation efficiency of crude oil was found as 88%, 92% and 97% for strain AS2, AS3 and AS4 respectively, with the optimum temperature of 37 degrees C and pH 7. FTIR confirm the BS belongs to lipopeptide in nature. GCMS reveals that three isolates degraded the lower to higher molecular weight of the crude oil (C-8 to C-28) effectively. Results showed that use of BS in electokinetic remediation enhance the biodegradation rate of crude oil contaminated soil about 92% than EK (60%) in 2 days operation. BS enhances the solubilization of hydrocarbon and it leads to the faster electro-migration of hydrocarbon to the anodic compartment, which was confirmed by the presence of higher total organic content than the EK. This study proven that the BIO-EK combined with BS can be used to enhance in situ bioremediation of petroleum contaminated soils. | Prakash, Arumugam Arul; Prabhu, Natarajan Srinivasa; Rajasekar, Aruliah; Parthipan, Punniyakotti; AlSalhi, Mohamad S.; Devanesan, Sandhanasamy; Govarthanan, Muthusamy | Thiruvalluvar Univ, Dept Biotechnol, Environm Mol Microbiol Res Lab, Vellore 632115, Tamil Nadu, India; Bharathidasan Univ, Dept Biotechnol & Genet Engn, Tiruchirappalli 620024, Tamil Nadu, India; Pondicherry Univ, Electrochem Energy Res Lab, Ctr Nanosci & Technol, Pondicherry 605014, India; King Saud Univ, Dept Phys & Astron, Coll Sci, Res Chair Laser Diag Canc, POB 2455, Riyadh 11451, Saudi Arabia; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea | Muthusamy, Govarthanan/C-1491-2014; Natarajan, Srinivasa/ABC-6687-2020; Aruliah, Rajasekar/E-4568-2015; Devanesan, Sandhanasamy/ABH-3378-2021; Punniyakotti, Parthipan/AAZ-3749-2021; Devanesan, Dr. Sandhanasamy/ABH-3378-2021; Govarthanan, Muthusamy/C-1491-2014 | 57209198571; 57218103955; 55928874800; 57193152696; 10440259800; 55279721800; 54881927600 | gova.muthu@gmail.com; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 405 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 3.46 | 2025-07-30 | 70 | 81 | Biosurfactant; Bio-electrokinetic; Crude oil; Biodegradation; Bioremediation | DEGRADING BACTERIA; BIOREMEDIATION; DEGRADATION; BIODEGRADATION; OPTIMIZATION; CORROSION; STEEL; WATER | Bio-electrokinetic; Biodegradation; Bioremediation; Biosurfactant; Crude oil | Bacillus; Biodegradation, Environmental; Hydrocarbons; Petroleum; Soil; Soil Microbiology; Soil Pollutants; Surface-Active Agents; Bacillus licheniformis; Bacillus subtilis; Bacillus velezensis; Bacteria (microorganisms); Bacteria; Bacteriology; Biodegradation; Biomolecules; Bioremediation; Biotechnology; Efficiency; Electrodynamics; Hydrocarbons; Soil pollution; Soils; Solubility; Surface active agents; 12 octadecadienoic acid; 2 piperidinone; biosurfactant; DNA 16S; dotriacontane; erucic acid; ester; heptacosane; hexatriacontane; hydrocarbon; lipopeptide; nonadecane; octacosane; octadecyl ester; oleic acid; oxalic acid; palmitic acid; petroleum; sea water; stearic acid; sulfurous acid; tetratetracontane; triacontane; tricosane; tritetracontane; hydrocarbon; surfactant; Bacillus licheniformis; Biodegradation efficiency; Crude oil-contaminated soils; Electrokinetic remediation; In-situ bioremediation; Petroleum-contaminated soil; Remediation efficiency; Total organic contents; bacterium; biodegradation; contaminated land; crude oil; electrokinesis; hydrocarbon; marine environment; petroleum hydrocarbon; soil remediation; surfactant; Bacillus licheniformis; Bacillus subtilis; Bacillus velezensis; bacterial growth; bacterial strain; bacterium identification; bacterium isolate; bacterium isolation; biodegradation; bioelectrokinetics; bioremediation; controlled study; Fourier transform infrared spectroscopy; gene sequence; mangrove; marine bacterium; mass fragmentography; molecular weight; nonhuman; pH; retention time; soil pollution; solubilization; temperature; total organic carbon; water sampling; Bacillus; bioremediation; microbiology; soil; soil pollutant; Crude oil | English | 2021 | 2021-03-05 | 10.1016/j.jhazmat.2020.124061 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Biodegradation and metabolic pathway of anthraquinone dyes by Trametes hirsuta D7 immobilized in light expanded clay aggregate and cytotoxicity assessment | Biodegradation and metabolic pathways of three anthraquinone dyes, Reactive Blue 4 (RB4), Remazol Brilliant Blue - R (RBBR), and Acid Blue 129 (AB129) by Trametes hirsuta D7 fungus immobilized in light expanded clay aggregate (LECA) were investigated. Morphological characteristics observed with scanning electron microscope (SEM) showed successful immobilization of the fungus in LECA. Based on UV absorbance measurement, immobilized T. hirsuta D7 effectively degraded 90%, 95%, and 96% of RB4, RBBR and AB129, respectively. Metabolites were identified with high-resolution mass spectrometry (HRMS) and degradation pathway of the dyes by T. hirsuta D7 was proposed. Toxicity assay on human dermal fibroblast (HDF) showed that anthraquinone dyes exhibits significant toxicity of 35%, 40%, and 34% reduction of cell viability by RB4, RBBR, and AB129, respectively. Fungal treatment resulted in an abatement of the toxicity and cell viability was increased up to 94%. The data clearly showed the effectiveness of immobilized T. hirsuta D7 in LECA on detoxification of anthraquinone dyes. This study provides potential and fundamental understanding of wastewater treatment using the newly isolated fungus T. hirsuta D7. | Alam, Rafiqul; Ardiati, Fenny Clara; Solihat, Nissa Nurfajrin; Alam, Md Badrul; Lee, Sang Han; Yanto, Dede Heri Yuli; Watanabe, Takashi; Kim, Sunghwan | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Indonesian Inst Sci LIPI, Res Ctr Biomat, Cibinong 16911, Indonesia; Kyungpook Natl Univ, Grad Sch, Dept Food Sci & Biotechnol, Daegu 41566, South Korea; Kyoto Univ, Res Inst Sustainable Humanosphere, Kyoto 6110011, Japan; Mass Spectrometry Converging Res Ctr & Green Nano, Daegu 41566, South Korea | ; Lee, Seung Eun/ABG-1607-2021; Kim, Sunghwan/HKN-9812-2023; Solihat, Nissa/GVT-7174-2022; Yanto, Dede/AAB-9415-2021; Alam, Md Badrul/AFL-7668-2022 | 57219723992; 57211191713; 57199653322; 56706777100; 57221453703; 55909235000; 57125173500; 57203772967 | dede@biomaterial.lipi.go.id;sunghwank@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 405 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 2.34 | 2025-07-30 | 48 | 56 | Anthraquinone dyes; Biodegradation pathway; Detoxification; HRMS; Trametes Hirsuta D7 | Anthraquinone dyes; Biodegradation pathway; Detoxification; HRMS; Trametes Hirsuta D7 | Anthraquinones; Biodegradation, Environmental; Clay; Coloring Agents; Humans; Laccase; Metabolic Networks and Pathways; Polyporaceae; Trametes; Senna hirsuta hirsuta; Trametes hirsuta; Aggregates; Aromatic compounds; Cell culture; Detoxification; Dyes; Ketones; Mass spectrometry; Metabolism; Metabolites; Scanning electron microscopy; Toxicity; Uranium metallography; Vanadium metallography; Wastewater treatment; acid blue 129; anthraquinone derivative; dye; laccase; reactive blue 4; remazol brilliant blue r; anthraquinone derivative; coloring agent; Cytotoxicity assessment; Degradation pathways; Expanded clay aggregates; High resolution mass spectrometry; Human dermal fibroblasts; Light expanded clay aggregates (LECA); Morphological characteristic; Remazol brilliant blues; biodegradation; cell component; detection method; dye; fungus; immobilization; metabolism; morphology; secondary metabolite; toxicity; wastewater; wastewater treatment; animal cell; biodegradation; C2C12 cell line; chemical structure; cytotoxicity; decolorization; electrospray mass spectrometry; HDF cell line; human; human cell; immobilization; light absorption; mass spectrometry; MDCK cell line; morphological trait; nonhuman; skin fibroblast; toxicity assay; Trametes hirsuta; ultraviolet radiation; waste water management; bioremediation; clay; metabolism; Polyporaceae; Trametes; Biodegradation | English | 2021 | 2021-03-05 | 10.1016/j.jhazmat.2020.124176 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Bioelectricity generation by natural microflora of septic tank wastewater (STWW) and biodegradation of persistent petrogenic pollutants by basidiomycetes fungi: An integrated microbial fuel cell system | The microbial fuel cell is a unique advantageous technology for the scientific community with the simultaneous generation of green energy along with bioelectroremediation of persistent hazardous materials. In this work, a novel approach of integrated system with bioelectricity generation from septic tank wastewater by native microflora in the anode chamber, while Psathyrella candolleana with higher ligninolytic enzyme activity was employed at cathode chamber for the biodegradation of polycyclic aromatic hydrocarbons (PAHs). Six MFC systems designated as MFC1, MFC2, MFC3, MFC4, MFC5, and MFC6 were experimented with different conditions. MFC1 system using natural microflora of STWW (100%) at anode chamber and K3[Fe(CN)6] as cathode buffer showed a power density and current density of 110 ? 10 mW/m2 and 90 ? 10 mA/m2 respectively. In the other five MFC systems 100% STWW was used at the anode and basidiomycetes fungi in the presence or absence of individual PAHs (naphthalene, acenaphthene, fluorene, and anthracene) at the cathode. MFC2, MFC3, MFC4, MFC5, and MFC6 had showed power density of 132 ? 17 mW/m2, 138 ? 20 mW/m2, 139 ? 25 mW/m2, and 147 ? 10 mW/m2 respectively. MFC2, MFC3, MFC4, MFC5, and MFC6 had showed current density of 497 ? 17 mA/m2, 519 ? 10 mA/m2, 522 ? 21 mA/m2 and 525 ? 20 mA/m2 respectively. In all the MFC systems, the electrochemical activity of anode biofilm was evaluated by cyclic voltammetry analysis and biofilms on all the MFC systems electrode surface were visualized by confocal laser scanning microscope. Biodegradation of PAHs during MFC experimentations in the cathode chamber was estimated by UV?Vis spectrophotometer. Overall, MFC6 system achieved maximum power density production of 525 ? 20 mA/m2 with 77% of chemical oxygen demand removal and 54% of coulombic efficiency at the anode chamber and higher anthracene biodegradation (62 ? 1.13%) at the cathode chamber by the selected Psathyrella candolleana at 14th day.

| ○ | ○ | Article | Biological mediated synthesis of RGO-ZnO composites with enhanced photocatalytic and antibacterial activity | In this study, we reported the biological approach to synthesis of ZnO nanorod (NR) on the reduced graphene oxide (RGO) for photocatalytic, antibacterial activity and hydrogen production under sunlight. Bacillus subtilis played a vital role in the production of biogenic ammonia from synthetic urine and utilized for the synthesis of ZnONR on the RGO sheet. The morphological study revealed that RGO sheets displayed a tremendous role in anchoring ZnONR. XRD patterns showed the ZnO crystal phase on the RGO sheets. XPS and Raman spectra confirmed that the bio-hydrothermal method as suitable for GO converted into RGO. The transient photocurrent and I/V measurement are exhibited as an increment on the RGO-ZnONR compared to ZnONR. The RGO-ZnONR composites showed excellent performance with decolorization of MB and textile dyes and efficient control of the E. coli and S. aureus. RGO-ZnONR exhibited remarkable noted as a higher photocatalytic hydrogen evolution rate (940 mu mol/h/g(cat)) than the ZnONR (369.5 mu mol/h/g (cat)). As a result of photocatalytic performance to correlate with sunlight intensity was extensively studied. RGO plays an essential role in interface electron transfer from sunlight to ZnONR for enhancing center dot OH radical formation to cleavage of dye color substance and eradicated bacterial cells. | Dhandapani, Perumal; AlSalhi, Mohamad S.; Karthick, Ramalingam; Chen, Fuming; Devanesan, Sandhanasamy; Kim, Woong; Rajasekar, Aruliah; Ahmed, Mukhtar; Aljaafreh, Mamduh J.; Muhammad, Atif | Thiruvalluvar Univ, Dept Biotechnol, Environm Mol Microbiol Res Lab, Vellore 632115, Tamil Nadu, India; King Saud Univ, Coll Sci, Dept Phys & Astron, POB 2455, Riyadh 11451, Saudi Arabia; South China Normal Univ, Sch Phys & Telecommun Engn, Guangdong Engn Technol Res Ctr Efficient Green En, Guangdong Prov Key Lab Quantum Engn & Quantum Mat, Guangzhou 510006, Peoples R China; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; King Saud Univ, Coll Sci, Cent Lab, Dept Zool, POB 2455, Riyadh 11451, Saudi Arabia | Aruliah, Rajasekar/E-4568-2015; Devanesan, Dr. Sandhanasamy/ABH-3378-2021; Perumal, Dhandapani/L-4325-2013; J., aljaafreh/HOF-9737-2023; Ahmed, Dr. Mukhtar/F-7056-2010; Devanesan, Sandhanasamy/ABH-3378-2021; Atif, Dr/C-4789-2013; R, KARTHICK/AAS-1717-2021; alsalhi, mohamad/M-5013-2019 | 36179531500; 10440259800; 57200885320; 57193337129; 55279721800; 55581636400; 55928874800; 7402831261; 57193846917; 59435281900 | rajasekargood@gmail.com; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 409 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 2.49 | 2025-07-30 | 55 | 58 | Biogenic ammonia; RGO-ZnONR; Decolorization of dye; Antibacterial activity; Hydrogen production | Antibacterial activity; Biogenic ammonia; Decolorization of dye; Hydrogen production; RGO-ZnONR | Anti-Bacterial Agents; Escherichia coli; Graphite; Staphylococcus aureus; Zinc Oxide; Bacillus subtilis; Bacteria (microorganisms); Escherichia coli; Staphylococcus aureus; Ammonia; Bacteriology; Dyes; Electron transport properties; Escherichia coli; Free radical reactions; Free radicals; Graphene; II-VI semiconductors; Nanorods; Oxide minerals; Photobiological hydrogen production; Photocurrents; Zinc oxide; ammonia; graphene oxide; hydrogen; hydroxyl radical; nanorod; reduced graphene oxide; zinc oxide; antiinfective agent; graphene oxide; graphite; Anti-bacterial activity; Biological approach; Hydrothermal methods; Morphological study; Photocatalytic hydrogen evolution; Photocatalytic performance; Reduced graphene oxides (RGO); Transient photocurrents; ammonia; antimicrobial activity; composite; concentration (composition); dye; hydrogen; performance assessment; ammonia formation; antibacterial activity; Bacillus subtilis; bacterial cell; comparative study; electron transport; Escherichia coli; field emission scanning electron microscopy; hydrogen evolution; nonhuman; photocatalysis; Raman spectrometry; Staphylococcus aureus; sunlight; synthesis; urine; Photocatalytic activity | English | 2021 | 2021-05-05 | 10.1016/j.jhazmat.2020.124661 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Colloidal activated carbon as a highly efficient bifunctional catalyst for phenol degradation | A preparation of colloidal activated carbon (CAC) for phenol remediation from groundwater was introduced. The CAC prepared by a simple pulverization technique was an excellent metal-free catalyst for persulfate (PS) activation due to high contact surface area. The removal efficiency of phenol in the PS/CAC system (similar to 100%) was higher than that in the PS/activated carbon (AC) system (90.1%) and was superior to the conventional PS/Fe2+ system (27.9%) within 30 min. The phenol removal reaction occurred both in bulk solution and at the surface of the CAC, as confirmed by Langmuir-Hinshelwood (L-H) kinetic model fitting, FT-IR, and electron spin resonance (ESR) analyses. The downsizing of particle size from AC to CAC played a critical role in the radical oxidation mechanism by leading to the formation of predominant superoxide radical (O-2(center dot-)) species in the PS/CAC system. Anions NO3-, SO42-, and Cl- slightly inhibited the phenol removal efficiency, whereas CO32-, HCO3- and PO43- did not. Ferulic acid (C10H10O4) was detected as an organic byproduct of phenol oxidation. The use of CAC as a metal-free bifunctional catalyst has an important implication in the PS activation for phenol degradation in groundwater. | Septian, Ardie; Kumar, Alam Venugopal Narendra; Sivasankar, Annamalai; Choi, Jiyeon; Hwang, Inseong; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea; Pusan Natl Univ, Dept Civil & Environm Engn, Busan 46241, South Korea | ; Septian, Ardie/HGB-8696-2022; Annamalai, Sivasankar/G-7823-2016 | 57201503612; 39262149400; 56388546200; 57211707591; 7201615105; 23019870800 | wshin@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 414 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 2.05 | 2025-07-30 | 44 | 44 | Colloidal activated carbon; Radical; Phenol degradation; Persulfate | IN-SITU REMEDIATION; PERSULFATE OXIDATION; ORGANIC CONTAMINANTS; REACTIVE RADICALS; FERULIC ACID; WATER; GROUNDWATER; SULFATE; ADSORPTION; TRICHLOROETHYLENE | Colloidal activated carbon; Persulfate; Phenol degradation; Radical | Activated carbon; Catalysts; Chemical activation; Efficiency; Electron spin resonance spectroscopy; Groundwater; Magnetic moments; Particle size; Particle size analysis; Phenols; Sols; activated carbon; ferrous ion; ferulic acid; ground water; nitrate; oxygen; phenol; superoxide; Bi-functional catalysts; Contact surface area; Metal-free catalysts; Organic byproducts; Phenol degradation; Radical oxidation; Removal efficiencies; Superoxide radical; activated carbon; byproduct; catalyst; degradation; organic compound; oxidation; particle size; phenol; pollutant removal; reaction kinetics; Article; catalyst; degradation; electron spin resonance; oxidation; particle size; surface area; Biodegradation | English | 2021 | 2021-07-15 | 10.1016/j.jhazmat.2021.125474 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Review | Coronavirus in water media: Analysis, fate, disinfection and epidemiological applications | Considerable attention has been recently given to possible transmission of SARS-CoV-2 via water media. This review addresses this issue and examines the fate of coronaviruses (CoVs) in water systems, with particular attention to the recently available information on the novel SARS-CoV-2. The methods for the determination of viable virus particles and quantification of CoVs and, in particular, of SARS-CoV-2 in water and wastewater are discussed with particular regard to the methods of concentration and to the emerging methods of detection. The analysis of the environmental stability of CoVs, with particular regard of SARS-CoV-2, and the efficacy of the disinfection methods are extensively reviewed as well. This information provides a broad view of the state-of-the-art for researchers involved in the investigation of CoVs in aquatic systems, and poses the basis for further analyses and discussions on the risk associated to the presence of SARS-CoV-2 in water media. The examined data indicates that detection of the virus in wastewater and natural water bodies provides a potentially powerful tool for quantitative microbiological risk assessment (QMRA) and for wastewater-based epidemiology (WBE) for the evaluation of the level of circulation of the virus in a population. Assays of the viable virions in water media provide information on the integrity, capability of replication (in suitable host species) and on the potential infectivity. Challenges and critical issues relevant to the detection of coronaviruses in different water matrixes with both direct and surrogate methods as well as in the implementation of epidemiological tools are presented and critically discussed. © 2021 The Authors | Buonerba, Antonio; Corpuz, Mary Vermi Aizza; Ballesteros, Florencio; Choo, Kwang-Ho; Hasan, Shadi W.; Korshin, Gregory V.; Belgiorno, Vincenzo; Barceló, Damià; Naddeo, Vincenzo | Sanitary Environmental Engineering Division (SEED), Department of Civil Engineering, University of Salerno, Via Giovanni Paolo II, Fisciano, SA, Italy, Inter-University Centre for Prediction and Prevention of Relevant Hazards (Centro Universitario per la Previsione e Prevenzione Grandi Rischi, C.U.G.RI.), Via Giovanni Paolo II, Fisciano, SA, Italy; Environmental Engineering Program, National Graduate School of Engineering, University of the Philippines, 1101 Diliman, Quezon City, Philippines; Environmental Engineering Program, National Graduate School of Engineering, University of the Philippines, 1101 Diliman, Quezon City, Philippines; Department of Environmental Engineering, Kyungpook National University (KNU), 80 Daehak-ro, Bukgu, Daegu, 41566, South Korea; Center for Membranes and Advanced Water Technology (CMAT), Department of Chemical Engineering, Khalifa University of Science and Technology, Abu Dhabi, United Arab Emirates; Department of Civil and Environmental Engineering, University of Washington, Box 352700, Seattle, 98105-2700, WA, United States; Sanitary Environmental Engineering Division (SEED), Department of Civil Engineering, University of Salerno, Via Giovanni Paolo II, Fisciano, SA, Italy; Catalan Institute for Water Research (ICR-CERCA), H2O Building, Scientific and Technological Park of the University of Girona, Emili Grahit 101, Girona, 17003, Spain; Sanitary Environmental Engineering Division (SEED), Department of Civil Engineering, University of Salerno, Via Giovanni Paolo II, Fisciano, SA, Italy | 36670901300; 57218353260; 36664314600; 7102083272; 35738779100; 7003696629; 6508019638; 36013249500; 57225215311 | vnaddeo@unisa.it; | Journal of Hazardous Materials | J HAZARD MATER | 0304-3894 | 1873-3336 | 415 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 1.03 | 2025-07-30 | 57 | Concentration; Coronavirus; Detection; Disinfection; Drinking water; Environment; Epidemiology; Hazards; Infectivity; Persistence; SARS-CoV-2; Viable virus; Wastewater | COVID-19; Disinfection; Humans; SARS-CoV-2; Waste Water; Wastewater-Based Epidemiological Monitoring; Water; Coronavirus; SARS coronavirus; Concentration (process); Disinfection; Epidemiology; Population statistics; Risk assessment; Viruses; Wastewater; virus RNA; water; Concentration; Coronaviruses; Detection; Environment; Infectivity; Media analysis; Persistence; SARS-CoV-2; Viable virus; Water media; disinfection; epidemiology; health risk; risk assessment; risk factor; severe acute respiratory syndrome; spatiotemporal analysis; virus; wastewater; wastewater treatment; coronavirus disease 2019; disinfection; environmental impact; human; infection risk; microbiological examination; nonhuman; persistent virus infection; quantitative analysis; Review; risk assessment; sedimentation; surface area; ultraviolet radiation; virion; virus detection; virus inactivation; virus particle; wastewater; water supply; Potable water | English | Final | 2021 | 10.1016/j.jhazmat.2021.125580 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | Article | Development of a real-time automated monitoring system for managing the hazardous environmental pollutants at the construction site | The management of noise, vibration, and dust, which are hazardous pollutants from construction sites, is es-sential to minimize the health damage of the nearby residents and the economic damage of construction companies due to pollutants from construction sites. For the effective management of hazardous pollutants, their emissions from construction sites must be identified immediately and accurately. Therefore, this study developed a real-time automated monitoring system named "MOnitoring for Noise, Vibration, and Dust (MONVID)" for comprehensively measuring the hazardous environmental pollutants and managing them in real-time. Toward this end, the optimal design of MONVID was planned and customized considering mobility, usability, and economy. Also, for the field application of the developed MONVID, its feasibility was verified by comparing its techno-economic performance with that of the conventional measurement system through experiments. Based on the results of the experiment and performance evaluation, it was concluded that MONVID is a feasible and economical construction pollutant measurement system with reliable technical performance and improved mobility and usability compared to the conventional measurement system. This study has significant contributions to the development of the first platform (including hardware, sensor network, and software) for the integrated real-time automated monitoring of the environmental performance of construction sites. | Kang, Hyuna; Sung, Seulki; Hong, Juwon; Jung, Seunghoon; Hong, Taehoon; Park, Seon; Lee, Dong-Eun | Yonsei Univ, Dept Architecture & Architectural Engn, Seoul, South Korea; Kyungpook Natl Univ, Sch Arch Civil Environm & Energy, 1370 Sangyegk Dong, Daegu 702701, South Korea | Hong, Taehoon/E-9169-2012 | hyuna_kang@yonsei.ac.kr;seulki0507@yonsei.ac.kr;juwonae@yonsei.ac.kr;saber21@yonsei.ac.kr;hong7@yonsei.ac.kr;hspark@yonsei.ac.kr;dolee@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 402 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 37 | Real-time automated monitoring system; Environmental pollutants; Construction site; Sensor network; Field application | CONDENSER MICROPHONE; BETA-ATTENUATION; NOISE; DUST; PREDICTION; VIBRATION; OPTIMIZATION; POLLUTION; EXPOSURE; MODEL | English | 2021 | 2021-01-15 | 10.1016/j.jhazmat.2020.123483 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Development of polystyrene coated persulfate slow-release beads for the oxidation of targeted PAHs: Effects of sulfate and chloride ions | In this study, we synthesized polystyrene coated persulfate polyacrylonitrile beads (PC-PSPANBs) to control persulfate (PS) release for targeted PAHs' degradation in a batch reactor. Initially, the persulfate release rate (ksr = 20.553 h-1) from PSPANBs was fast, but coating the PSPANBs with polystyrene controlled PS release rate (ksr 1/4 2.841 h-1), nearly ten times slower than without coating. When Fe(II) activated PC-PSPANBs applied for 12 h degradation of acenaphthene (ACE), 2-methlynaphthalene (2-MN) and dibenzofuran (DBF), the optimum percent removal efficiencies (% R.Es) were as ACE (82.12%) > DBF (68.57%) > 2-MN (58.80%) and the optimum degradation rate constants (kobs) were found as ACE (11.348 h-1) > 2-MN (3.441 h-1) > DBF (1.101 h-1). The effect of SO42- and Cl- on ACE degradation showed that % R.E and kobs were enhanced with increasing anionic concentrations. The maximum % R.E was achieved for SO42- (76.24%) > Cl-(65.51%), but the highest kobs was in case of Cl- (1.536 h-1) > SO42- (0.510 h-1). The effectiveness of PS release longevity was also found because net degradations of ACE and DBF after first spiking were 12 mg L-1 and 16 mg L-1, while after second spiking were 18 mg L-1 and 10 mg L-1, respectively. | Abbas, Wajahat; Abbas, Shujaat; Nawaz, Mohsin; Azam, Mudassar; Oh, Jae-Min; Shahzad, Asif | Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea; Inst Southern Punjab, Civil Engn Dept, Multan, Pakistan; Muhammad Nawaz Shareef Univ Agr, Dept Agr Engn, Old Shujabad Rd, Multan 60000, Pakistan; Univ Punjab, Inst Chem Engn & Technol, Lahore 54590, Pakistan; Dongguk Univ, Dept Energy & Mat Engn, Seoul 04620, South Korea | ; Azam, Maryam/HNP-4769-2023 | 57224527022; 57225757876; 55235830600; 57193438857; 7402155053; 57190382338 | asifshzd8@dongguk.edu; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 416 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 0.63 | 2025-07-30 | 24 | 24 | Persulfate slow-release beads; Ferrous; PAHs; Sulfate ion; Chloride ion | POLYCYCLIC AROMATIC-HYDROCARBONS; DEGRADATION; BTEX; PEROXYMONOSULFATE; EXPOSURE; KINETICS | Chloride ion; Ferrous; PAHs; Persulfate slow-release beads; Sulfate ion | Chlorides; Oxidation-Reduction; Polystyrenes; Sulfates; Water Pollutants, Chemical; Batch reactors; Coatings; Degradation; Ions; Iron compounds; Polycyclic aromatic hydrocarbons; Polystyrenes; Rate constants; Sulfur compounds; acenaphthene; chloride ion; dibenzofuran; ground water; organic matter; paraffin; peroxydisulfate potassium; polyacrylonitrile; polystyrene; sulfate; chloride; polystyrene derivative; sulfate; Acenaphthene; Chloride ions; Dibenzofurans; Ferrous; Persulphate; Persulphate slow-release bead; Release rate; Slow release; SO$-4$/$+2-$; Sulphate ion; chloride; coating; concentration (composition); degradation; iron; longevity; oxidation; pollutant removal; polymer; sulfate; Article; chemical analysis; chemical reaction kinetics; comparative study; controlled study; limit of detection; longevity; oxidation; photodegradation; solvent extraction; surface property; oxidation reduction reaction; water pollutant; Chlorine compounds | English | 2021 | 2021-08-15 | 10.1016/j.jhazmat.2021.125879 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Enhanced sustainable electro-generation of a Ni (I) homogeneous electro-catalyst at a silver solid amalgam electrode for the continuous degradation of N2O, NO, DCM, and CB pollutants | This paper reports the sustainable and enhanced generation of a Ni(I) active electro-catalyst using AgSAE as a cathode material for the sustainable degradation of N2O, NO, dichloromethane (DCM), and chlorobenzene (CB) by electroscrubbing in a series operation. The AgSAE electrode showed 1.66 times higher Ni(I) formation than the Ag metal electrode. The AgSAE achieved 20% +/- 2% Ni(I) generation in a highly concentrated alkaline medium, whereas Ag metal only achieved 12% +/- 2% Ni(I) generation at the same current density. Electrochemical impedance spectroscopy and voltammetric studies determined that the kinetics of the charge-transfer reaction was also preferential at the AgSAE, with the cathodic peak at -1.26 V vs. Ag/AgCl confirming Ni(I) formation. Initially, the change in the oxygen reduction potential and reduction efficiency of Ni(I) confirmed the removal of N2O, NO, DCM and CB. In addition, the gas Fourier transform infrared (FTIR) spectrum revealed 99.8% removal efficiency of toxic pollutants. Therefore, the regeneration of Ni(I) confirmed the sustainable removal of toxic pollutants. Furthermore, the FTIR spectra revealed the formation of NH3 during the reduction of N2O and NO. On the other hand, DCM and CB were reduced to benzene derivatives in the solution phase. In addition, a plausible reduction mechanism was derived. As a result, the AgSAE cathode exhibited two-fold higher removal efficiency of N2O, NO, DCM, and CB than the previously reported electrodes. | Silambarasan, P.; Ramu, A. G.; Govarthanan, M.; Jung, K.

| ○ | ○ | Article | Facile fabrication of (2D/2D) MoS2@MIL-88(Fe) interface-driven catalyst for efficient degradation of organic pollutants under visible light irradiation | The present investigation describes the photocatalytic degradation of methylene blue (MB) and rhodamine-B (RhB) using molybdenum disulfide (MoS2) anchored metal-organic frameworks (MOFs) under visible light irradiation. Herein, MIL-88(Fe) was successfully modified with MoS2 to yield a novel heterogeneous MoS2@MIL88(Fe) hybrid composite. The prepared catalyst enhances the superior photocatalytic activity than the pristine form of MoS2 and MIL-88(Fe) framework. The physico-chemical properties of the prepared catalyst were analytically investigated and the results exhibit greater photocatalytic efficiency towards the chosen dyes, with an optical band gap of 2.75 eV. The MoS2 and MIL-88(Fe) framework could act as efficient oxidation and reduction sites in the as-synthesized MoS2@MIL-88(Fe) composite, and generated the non-toxic by-products such as hydroxyl ((OH)-O-center dot), and superoxide species (O-center dot(2)-) for the mineralization of MB and RhB dyes. The degradation kinetics showed that the dye system followed a pseudo-first-order model which is well supported by the Langmuir-Hinshelwood mechanism. Moreover, the reusability studies showed excellent photocatalytic activity after five cycles. Finally, the photocatalytic degradation mechanism of MB and RhB dyes was suggested. | Govarthanan, M.; Mythili, R.; Kim, Woong; Alfarraj, Saleh; Alharbi, Sulaiman Ali | Kyungpook Natl Univ, Dept Environm Engn, Daegu, South Korea; Mahendra Arts & Sci Coll, PG & Res Dept Biotechnol, Kalippatti, Tamil Nadu, India; King Saud Univ, Coll Sci, Zool Dept, Riyadh 11451, Saudi Arabia; King Saud Univ, Coll Sci, Dept Bot & Microbiol, POB 2455, Riyadh 11451, Saudi Arabia | Muthusamy, Govarthanan/C-1491-2014; Govarthanan, Muthusamy/C-1491-2014; Alfarraj, Saleh/AHE-7705-2022; alharbi, sulaiman/KHE-3282-2024; R, Mythili/KAM-6234-2024 | 54881927600; 56765761500; 55581636400; 23481183500; 59157644200 | elshine@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 414 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 4.93 | 2025-07-30 | 119 | 121 | MoS2; MIL-88(Fe); Photocatalytic degradation; Visible light; Dyes | MOLYBDENUM-DISULFIDE MOS2; PHOTOCATALYTIC DYE DEGRADATION; TEXTILE WASTE-WATER; METHYLENE-BLUE; RHODAMINE-B; REMOVAL; NANOCOMPOSITES; ADSORBENTS; ADSORPTION; FRAMEWORKS | Dyes; MIL-88(Fe); MoS<sub>2</sub>; Photocatalytic degradation; Visible light | Aromatic compounds; Catalyst activity; Chemical analysis; Crystalline materials; Dyes; Energy gap; Iron compounds; Irradiation; Layered semiconductors; Light; Organic pollutants; Organometallics; Photocatalytic activity; Photodegradation; Reusability; Rhodium compounds; Sulfur compounds; disulfide; hydroxyl group; methylene blue; molybdenum; rhodamine B; superoxide; Facile fabrication; Methylene Blue; MIL-88(fe); MoS$-2$; Organics; Photo catalytic degradation; Rhodamine B dye; Visible light; Visible-light irradiation; ]+ catalyst; catalysis; catalyst; dye; irradiation; mineralization; molybdenum; oxidation; photodegradation; reaction kinetics; visible spectrum; Article; catalyst; controlled study; degradation; degradation kinetics; hybrid; irradiation; light; microtechnology; mineralization; oxidation; photocatalysis; physical chemistry; reduction (chemistry); water pollutant; Molybdenum compounds | English | 2021 | 2021-07-15 | 10.1016/j.jhazmat.2021.125522 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Implications for the PET decomposition mechanism through similarity and dissimilarity between PETases from Rhizobacter gummiphilus and Ideonella sakaiensis | The development of a superb polyethylene terephthalate (PET) hydrolyzing enzyme requires an accurate understanding of the PET decomposition mechanism. However, studies on PET degrading enzymes, including the PET hydrolase from Ideonella sakaiensis (IsPETase), have not provided sufficient knowledge of the molecular mechanisms for the hardly accessible substrate. Here, we report a novel PET hydrolase from Rhizobacter gummiphilus (RgPETase), which has a hydrolyzing activity similar to IsPETase toward microcrystalline PET but distinct behavior toward low crystallinity PET film. Structural analysis of RgPETase reveals that the enzyme shares the key structural features of IsPETase for high PET hydrolysis activity but has distinguished structures at the surface-exposed regions. RgPETase shows a unique conformation of the wobbling tryptophan containing loop (WW-loop) and change of the electrostatic surface charge on the loop dramatically affects the PET-degrading activity. We further show that effect of the electrostatic surface charge to the activity varies depending on locations. This work provides valuable information underlying the uncovered PET decomposition mechanism. | Sagong, Hye-Young; Son, Hyeoncheol Francis; Seo, Hogyun; Hong, Hwaseok; Lee, Donghoon; Kim, Kyung-Jin | Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat BioRes Grp, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU Inst Microorganisms, Daegu 41566, South Korea; Pohang Univ Sci & Technol, Pohang Accelerator Lab, Pohang, South Korea | ; Kim, Kyung-Jin/MVY-3405-2025 | 57006554000; 56015598000; 57189697998; 57208592877; 57207418964; 55510867400 | kkim@knu.ac.kr; | JOURNAL OF HAZARDOUS MATERIALS | J HAZARD MATER | 0304-3894 | 1873-3336 | 416 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 14.224 | 3.1 | 2.98 | 2025-07-30 | 65 | 67 | Polyethylene terephthalate; Enzyme; Environmental degradation; Molecular structure; Surface charge | CUTINASE-CATALYZED HYDROLYSIS; POLYETHYLENE TEREPHTHALATE; DEGRADATION; POLY(ETHYLENE-TEREPHTHALATE); DEGRADES; BACTERIUM; ENZYMES; POLYETHYLENETEREPHTHALATE; HYDROLASE; FUSION | Environmental degradation; Enzyme; Molecular structure; Polyethylene terephthalate; Surface charge | Burkholderiales; Hydrolases; Polyethylene Terephthalates; Ideonella; Amino acids; Crystallinity; Hydrolysis; Plastic bottles; Polyethylene terephthalates; Polyethylenes; Surface charge; arginine; hydrolase; polyethylene terephthalate; tryptophan; hydrolase; Decomposition mechanism; Degrading enzymes; Electrostatic surface charge; Hydrolyzing activity; Hydrolyzing enzymes; Low crystallinity; Microcrystallines; Molecular mechanism; Polyethylene-terephthalate films; Terephthalate; crystallinity; decomposition; enzyme; enzyme activity; rhizobacterium; Article; controlled study; crystal structure; enzymatic degradation; enzyme activity; gene expression system; hydrogen bond; hydrolysis; Ideonella sakaiensis; nonhuman; protein folding; Rhizobacter gummiphilus; Rhizobium; static electricity; surface charge; Burkholderiales; Enzymes | English | 2021 | 2021-08-15 | 10.1016/j.jhazmat.2021.126075 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
