○ ○ Article ⓘ Targeted toxicometabolomics of endosulfan sulfate in adult zebrafish (Danio rerio) using GC-MS/MS in multiple reaction monitoring mode ⓘ Endosulfan sulfate is a major oxidative metabolite of the chlorinated insecticide endosulfan. In this study, a targeted metabolomics approach was used to investigate the toxic mechanisms of endosulfan sulfate in adult zebrafish using the multiple reaction monitoring mode of a GC-MS/MS. The LC50 of endosulfan sulfate in adult zebrafish was determined and then zebrafish were exposed to endosulfan sulfate at one-tenth the L50 (0.1LC(50)) or the LC50 for 24 and 48 h. After exposure, the fish were extracted, derivatized and analyzed by GC-MS/MS for 379 metabolites to identify 170 metabolites. Three experimental groups (control, 0.1LC(50) and LC50) were clearly separated in PLS-DA score plots. Based on the VIP, ANOVA, and fold change results, 40 metabolites were selected as biomarkers. Metabolic pathways associated with those metabolites were identified using MetaboAnalyst 4.0 as follows: aminoacyl-tRNA biosynthesis, valine/leucine/isoleucine biosynthesis, citrate cycle, glycerolipid metabolism, and arginine/proline metabolism. Gene expression studies confirmed the activation of citrate cycle and glycerolipids metabolism. MDA levels of the exposed group significantly increased in oxidative toxicity assay tests. Such significant perturbations of important metabolites within key biochemical pathways must result in biologically hazardous effects in zebrafish. ⓘ Lee, Hwa-Kyung; Kim, Kyeongnam; Lee, Junghak; Lee, Jonghwa; Lee, Jiho; Kim, Sooyeon; Lee, Sung-Eun; Kim, Jeong-Han ⓘ Seoul Natl Univ, Dept Agr Biotechnol, Seoul 08826, South Korea; Seoul Natl Univ, Res Inst Agr & Life Sci, Seoul 08826, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Univ Massachusetts, Dept Vet & Anim Sci, Amherst, MA 01003 USA; Korea Conform Labs, Environm Med Ctr, Incheon 21999, South Korea; Korea Inst Toxicol, Gyeongnam Dept Environm Toxicol & Chem, Gyeongsangnam Do 52834, South Korea ⓘ JIHO, LEE/NKQ-2643-2025; Kim, Kyeongnam/KSM-2719-2024; Lee, Jong-Chan/AAJ-2401-2020 ⓘ 57211545599; 57191364349; 57193994062; 57201010974; 56341609900; 55862538300; 55890041600; 7601382100 ⓘ selpest@knu.ac.kr;kjh2404@snu.ac.kr; ⓘ JOURNAL OF HAZARDOUS MATERIALS ⓘ J HAZARD MATER ⓘ 0304-3894 1873-3336 389 SCIE ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES ⓘ 2020 10.588 3.5 1 2025-06-25 ⓘ 31 33 Targeted metabolomics; Endosulfan sulfate; Zebrafish; GC-MS/MS; Toxicometabolomics ⓘ NMR-BASED METABOLOMICS; APOPTOTIC CELL-DEATH; OXIDATIVE STRESS; GENE-EXPRESSION; TOXICITY; EXPOSURE; METABOLITE; PESTICIDE; BIOACCUMULATION; IDENTIFICATION ⓘ Endosulfan sulfate; GC-MS/MS; Targeted metabolomics; Toxicometabolomics; Zebrafish ⓘ Animals; Catalase; Endosulfan; Gas Chromatography-Mass Spectrometry; Gene Expression; Malondialdehyde; Metabolome; Metabolomics; Multivariate Analysis; Reactive Oxygen Species; Superoxide Dismutase; Tandem Mass Spectrometry; Water Pollutants, Chemical; Zebrafish; Danio rerio; Amino acids; Biochemistry; Biohazards; Biomolecules; Biosynthesis; Gene expression; Insecticides; Metabolism; Sulfur compounds; aminoacyl transfer RNA; arginine; endosulfan; endosulfan sulfate; glycerolipid; isoleucine; leucine; malonaldehyde; proline; unclassified drug; valine; catalase; endosulfan; endosulfan sulfate; malonaldehyde; reactive oxygen metabolite; superoxide dismutase; Endosulfan sulfate; GC-MS/MS; Metabolomics; Toxicometabolomics; Zebrafish; biochemistry; chlorination; cyprinid; endosulfan; gas chromatography; insecticide; mass spectrometry; metabolism; pesticide residue; sulfate; toxicity test; adult; amino acid metabolism; amino acid synthesis; animal experiment; Article; citric acid cycle; controlled study; ecotoxicity; gene expression; LC50; lipid metabolism; mass fragmentography; metabolomics; multiple reaction monitoring; nonhuman; oxidative stress; RNA synthesis; toxicity assay; zebra fish; animal; drug effect; genetics; mass fragmentography; metabolism; metabolome; metabolomics; multivariate analysis; procedures; tandem mass spectrometry; toxicity; water pollutant; zebra fish; Metabolites ⓘ English 2020 2020-05-05 10.1016/j.jhazmat.2020.122056 ⓘ 바로가기 바로가기 바로가기 바로가기

○ ○ Article ⓘ Fouling and performance of outer selective hollow fiber membrane in osmotic membrane bioreactor: Cross flow and air scouring effects ⓘ This study assessed impacts of cross-flow velocity (CFV) and air scouring on the performance and membrane fouling mitigation of a side-stream module containing outer-selective hollow fiber thin film composite forward osmosis membrane in osmosis membrane bioreactor (OMBR) system for urban wastewater treatment. CFV of draw solution was optimized, followed by the impact assessment of three CFVs on feed solution (FS) stream and periodic injection of air scouring into the side-stream module. Overall, the OMBR system exhibited high and stable performance with initial water flux of approximately 15 LMH, high removal efficiencies of bulk organic matter and nutrients. While FS's CFVs insignificantly affected the performance and membrane fouling, regular air scouring showed substantial impact with better performance and high efficiency in mitigating membrane fouling. These results indicated that periodic air scouring can be applied into the side-stream membrane module for efficient fouling mitigation without interruption the operation of the OMBR system. ⓘ Van Huy Tran; Lim, Sungil; Park, Myoung Jun; Han, Dong Suk; Phuntsho, Sherub; Park, Hyunwoong; Matsuyama, Hideto; Shon, Ho Kyong ⓘ UTS, Sch Civil & Environm Engn, CTWW, Sydney, NSW, Australia; Qatar Univ, Ctr Adv Mat, POB 2713, Doha, Qatar; Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea; Kobe Univ, Dept Chem Sci & Engn, Res Ctr Membrane & Film Technol, 1-1 Rokkodai, Kobe, Hyogo 6578501, Japan ⓘ Shon, Ho Kyong/P-7057-2015; Shon, Ho/P-7057-2015; Han, Dong SuK/AAX-9333-2021; Park, Hyunwoong/A-1247-2012; Matsuyama, Hideto/G-2357-2016; Lim, Sungil/AAK-3376-2020; PHUNTSHO, SHERUB/H-1064-2014 ⓘ 57211484362; 57192809480; 57211486333; 36139213900; 23971296800; 7601565583; 57201543303; 6701629946 ⓘ hokyong.shon-1@uts.edu.au; ⓘ BIORESOURCE TECHNOLOGY ⓘ BIORESOURCE TECHNOL ⓘ 0960-8524 1873-2976 295 SCIE AGRICULTURAL ENGINEERING;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENERGY & FUELS ⓘ 2020 9.642 3.6 0.7 2025-06-25 ⓘ 19 18 Outer-selective hollow fiber; Cross flow velocity; Air scouring; Osmotic membrane bioreactor; Membrane fouling ⓘ MUNICIPAL WASTE-WATER; OSMOSIS MEMBRANES; NUTRIENT REMOVAL; HYBRID SYSTEM; MICROFILTRATION; SALINITY; OMBR; DESALINATION; PROPENSITY; SEAWATER ⓘ Air scouring; Cross flow velocity; Membrane fouling; Osmotic membrane bioreactor; Outer-selective hollow fiber ⓘ Bioreactors; Membranes, Artificial; Osmosis; Waste Water; Water Purification; Bioconversion; Biological water treatment; Bioreactors; Chemicals removal (water treatment); Efficiency; Flow velocity; Membrane fouling; Osmosis; Osmosis membranes; Wastewater treatment; organic matter; Air scouring; Crossflow velocities; Forward osmosis membranes; Hollow fiber; Hollow fiber membranes; Membrane bioreactor; Removal efficiencies; Thin film composites; biofouling; bioreactor; composite; efficiency measurement; membrane; organic matter; performance assessment; wastewater; wastewater treatment; Article; fouling control; municipal wastewater; nutrient; osmosis; priority journal; salinity; urban area; waste water management; water quality; artificial membrane; bioreactor; osmosis; waste water; water management; Air ⓘ English 2020 2020-01 10.1016/j.biortech.2019.122303 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Isolation and characterization of novel indigenous facultative quorum quenching bacterial strains for ambidextrous biofouling control ⓘ Quorum quenching (QQ), the disruption of microbial communication, has proven to be effective as an innovative anti-biofouling strategy for membrane bioreactors (MBRs). However, QQ bacteria for anaerobic environments have not been extensively analyzed in previous research. This study thus investigated facultative QQ bacterial strains that exhibit potential for use in aerobic and anaerobic MBRs. Two novel QQ strains from the genus Pseudomonas (KS2 and KS10) were isolated from anaerobic digester sludge using signal molecules as the sole carbon source. The two QQ strains exhibited significant signal molecule degradation depending on the oxygen levels and demonstrated endogenous QQ activity, with KS2 producing lactonase and KS10 producing acylase. The QQ strains significantly reduced the formation of the biofilm generated by both Pseudomonas aeruginosa (PAO1) and real sludge. Facultative QQ strains have the potential to offer a more flexible option for effective biofouling control in both aerobic and anaerobic MBRs. ⓘ Shah, Syed Salman Ali; Choo, Kwang-Ho ⓘ Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Adv Inst Water Ind, 80 Daehak Ro, Daegu 41566, South Korea ⓘ Shah, Syed Salman Ali/JCE-1663-2023; Choo, Kwang-Ho/A-3456-2016 ⓘ 57215722996; 7102083272 ⓘ chookh@knu.ac.kr; ⓘ BIORESOURCE TECHNOLOGY ⓘ BIORESOURCE TECHNOL ⓘ 0960-8524 1873-2976 308 SCIE AGRICULTURAL ENGINEERING;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENERGY & FUELS ⓘ 2020 9.642 3.6 1.2 2025-06-25 ⓘ 33 35 Quorum quenching; Facultative bacteria; Membrane bioreactor; Biofouling; Signal molecule ⓘ SENSING SIGNAL MOLECULES; HOMOSERINE LACTONE ACYLASE; MEMBRANE BIOREACTOR; WASTE-WATER; OPERATION; REMOVAL; FLUX; MBR ⓘ Biofouling; Facultative bacteria; Membrane bioreactor; Quorum quenching; Signal molecule ⓘ Bacteria; Biofilms; Biofouling; Bioreactors; Quorum Sensing; Bacteria (microorganisms); Pseudomonas; Pseudomonas aeruginosa; Bacteria; Bioreactors; Molecules; Quenching; Anaerobic digester; Anaerobic environment; Biofouling control; Isolation and characterization; Membrane bioreactor; Microbial communications; Pseudomonas aeruginosa; Sole carbon source; anaerobic digestion; bacterium; biodegradation; biofilm; biofouling; detection method; enzyme; enzyme activity; membrane; microbial activity; sludge; anaerobic digestion; anaerobic sludge; Article; bacterial strain; bacterium isolate; biofilm; biofouling; carbon source; nonhuman; priority journal; Pseudomonas aeruginosa; quorum sensing; bacterium; bioreactor; quorum sensing; Biofouling ⓘ English 2020 2020-07 10.1016/j.biortech.2020.123269 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Reducing food waste in residential complexes using a pilot-scale on-site system ⓘ A pilot-scale on-site system combining biological treatment and a drying stage was applied to achieve mass reduction of food waste (FW) at an urban residential complex. The effectiveness of biodegrading the organic portion of FW via microorganisms existing in FW improved by 38.80% by controlling rates of FW loading and air-flow. In one stage of the on-site biological treatment, the major bacterial community was identified to be mesophilic and facultative; Lactobacillus was the most dominant genus, accounting for 78.1% of bacterial community. Total mass reduction of FW approached 90.15% by increasing removal of both moisture and the organic portion of FW. In addition, the solids and liquids of the final by-products have the potential to be recycled into resources such as fertilizer, a bio-solid refuse fuel or external carbon sources for wastewater treatment plants. The proposed decentralized system offers practical and environmental approaches for FW management in residential complexes. ⓘ Jeon, Dawoon; Chung, Kyungmi; Shin, Jingyeong; Park, Chang Min; Shin, Seung Gu; Kim, Young Mo ⓘ Gwangju Inst Sci & Technol, Sch Earth Sci & Environm Engn, Gwangju 500712, South Korea; GS E&C Res Inst, Bldg & Environm Res Team, 388 Baeok Daero Idong Myeon, Yongin, Gyeonggi Do, South Korea; Hanyang Univ, Dept Civil & Environm Engn, Seoul 04763, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Gyeongnam Natl Univ Sci & Technol, Future Convergence Technol Res Inst, Dept Energy Engn, Jinju 52725, South Korea ⓘ Park, Chang Min/CAA-8506-2022; Shin, Seung/ABD-4657-2020; Kim, Young Mo/HKF-1486-2023 ⓘ 57216874382; 57216887947; 57194702841; 57209588953; 36720773200; 57202258703 ⓘ youngmo@hanyang.ac.kr; ⓘ BIORESOURCE TECHNOLOGY ⓘ BIORESOURCE TECHNOL ⓘ 0960-8524 1873-2976 311 SCIE AGRICULTURAL ENGINEERING;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENERGY & FUELS ⓘ 2020 9.642 3.6 0.75 2025-06-25 ⓘ 22 22 Food waste; A pilot-scale on-site system; Microbial community; Mass reduction; By-product ⓘ THERMOPHILIC AEROBIC DIGESTION; ANAEROBIC CO-DIGESTION; FATTY-ACIDS PRODUCTION; MICROBIAL COMMUNITY; HYDROGEN-PRODUCTION; BROWN WATER; LIFE-CYCLE; FERMENTATION; LCA ⓘ A pilot-scale on-site system; By-product; Food waste; Mass reduction; Microbial community ⓘ Food; Garbage; Refuse Disposal; Waste Management; Waste Water; Bacteria (microorganisms); Lactobacillus; Biochemical engineering; Food waste; Housing; Thermal processing (foods); Urban growth; Waste treatment; Wastewater treatment; acetic acid; butyric acid; carbohydrate; fertilizer; lactic acid; lipid; propionic acid; refuse derived fuel; valeric acid; Bacterial community; Biological treatment; Carbon source; Decentralized system; Mass reduction; Onsite systems; Residential complexes; Wastewater treatment plants; bacterium; biodegradation; food waste; microbial community; residential location; waste treatment; Article; carbon source; chemical oxygen demand; controlled study; food waste; high throughput sequencing; Lactobacillus; mesophilic bacterium; microbial community; moisture; nonhuman; oxygen consumption; pH; priority journal; salinity; solids retention time; waste water treatment plant; food; waste; waste disposal; waste management; waste water; Bacteria ⓘ English 2020 2020-09 10.1016/j.biortech.2020.123497 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Simultaneous fermentation of galacturonic acid and five-carbon sugars by engineered Saccharomyces cerevisiae ⓘ Pectin-rich biomass has garnered attention as an alternative biomass source. However, some monomers derived from pectin-rich biomass, namely D-galacturonic acid, L-arabinose, and D-xylose, are not fermentable by industrial microorganisms such as Saccharomyces cerevisiae. The purpose of this study is to develop a S. cerevisiae strain capable of fermenting the pectin monomers. Expressions of eight heterologous genes and deletion of two endogenous genes, all of which were successfully completed by Cas9-based in vivo assembly and integration strategy, allowed the consumption of pectin monomers as sole carbon sources. To facilitate the consumption of galacturonic acid, which had the most limitations, the use of a co-substrate was tested using various sugars. As a result, we found that arabinose and xylose allowed simultaneous consumption of galacturonic acid. Based on intracellular metabolite profiling, it was concluded that the five-carbon sugars partially resolve the metabolic bottleneck of galacturonic acid. ⓘ Jeong, Deokyeol; Ye, Suji; Park, Heeyoung; Kim, Soo Rin ⓘ Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea ⓘ ; Jeong, Deokyeol/GLR-8021-2022; Kim, Soo Rin/X-2192-2019 ⓘ 57191332457; 57208240237; 57211334915; 36659584200 ⓘ soorinkim@knu.ac.kr; ⓘ BIORESOURCE TECHNOLOGY ⓘ BIORESOURCE TECHNOL ⓘ 0960-8524 1873-2976 295 SCIE AGRICULTURAL ENGINEERING;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENERGY & FUELS ⓘ 2020 9.642 3.6 1.05 2025-06-25 ⓘ 32 33 Citrus peel waste; Sugar beet pulp; Pectin; D-galacturonic acid; L-arabinose; Metabolic engineering; CRISPR/Cas9; Saccharomyces cerevisiae; Bioethanol ⓘ L-ARABINOSE; ETHANOL ⓘ Bioethanol; Citrus peel waste; CRISPR/Cas9; D-galacturonic acid; L-arabinose; Metabolic engineering; Pectin; Saccharomyces cerevisiae; Sugar beet pulp ⓘ Carbon; Ethanol; Fermentation; Glucose; Hexuronic Acids; Saccharomyces cerevisiae; Sugars; Xylose; Beta vulgaris subsp. vulgaris; Citrus; Saccharomyces cerevisiae; Bioethanol; Biomass; Carbon; Genes; Metabolic engineering; Metabolism; Metabolites; Microorganisms; Monomers; Sugar beets; Sugars; aldehyde dehydrogenase; arabinose; carbon; caspase 9; galacturonic acid; pectin; unclassified drug; xylitol dehydrogenase; xylose; xylose reductase; xylulokinase; alcohol; carbohydrate; carbon; galacturonic acid; glucose; hexuronic acid; Citrus peel; CRISPR/Cas9; D galacturonic acids; L-arabinose; Pectin; Sugar beet pulp; bioengineering; biofuel; biomass; chemical compound; fermentation; gene expression; metabolism; metabolite; microorganism; sugar; yeast; Article; Aspergillus niger; carbon source; catabolite repression; enzyme activity; fermentation; gene deletion; heterologous expression; metabolic engineering; nonhuman; pentose phosphate cycle; priority journal; Saccharomyces cerevisiae; upregulation; fermentation; Yeast ⓘ English 2020 2020-01 10.1016/j.biortech.2019.122259 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Sphingolipids Modulate Secretion of Glycosylphosphatidylinositol-Anchored Plasmodesmata Proteins and Callose Deposition ⓘ Plasma membranes encapsulated in the symplasmic nanochannels of plasmodesmata (PD) contain abundant lipid rafts, which are enriched with sphingolipids (SLs) and sterols. Reduction of sterols has highlighted the role played by lipid raft integrity in the intercellular trafficking of glycosylphosphatidylinositol (GPI)-anchored PD proteins, particularly in affecting callose enhancement. The presence of callose at PD is strongly attributed to the regulation of callose accumulation and callose degradation by callose synthases and beta-1,3-glucanases (BGs), respectively. SLs are implicated in signaling and membrane protein trafficking; however, the underlying processes linking SL composition to the control of symplasmic apertures remain unknown. The wide variety of SLs in plants prompted us to investigate which SL molecules are important for regulating symplasmic apertures in Arabidopsis (Arabidopsis thaliana). We introduced several potential SL pathway inhibitors and genetically modified SL contents using two independent SL pathway mutants. We were able to modulate callose deposition to control symplasmic connectivity through perturbations of SL metabolism. Alteration in glucosylhydroxyceramides or related SL composition particularly disturbed the secretory machinery for the GPI-anchored PdBG2 protein, resulting in an overaccumulation of callose. Moreover, our results revealed that SL-enriched lipid rafts link symplasmic channeling to PD callose homeostasis by controlling the targeting of GPI-anchored PdBG2. This study elevates our understanding of the molecular linkage underlying intracellular trafficking and precise targeting of GPI-anchored PD proteins incorporating glucosyl SLs. ⓘ Iswanto, Arya Bagus Boedi; Shon, Jong Cheol; Liu, Kwang Hyeon; Vu, Minh Huy; Kumar, Ritesh; Kim, Jae-Yean ⓘ Gyeongsang Natl Univ, Plant Mol Biol & Biotechnol Res Ctr, Div Appl Life Sci, BK21 Plus Program, Jinju 660701, South Korea; Kyungpook Natl Univ, Coll Pharm, Daegu 702701, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu 702701, South Korea; Korea Inst Toxicol, Environm Chem Res Grp, Jinju 52834, South Korea; Gyeongsang Natl Univ, Div Life Sci, Jinju 52828, South Korea; Univ Missouri, CS Bond Life Sci Ctr, Div Plant Sci, Columbia, MO 65201 USA ⓘ ; Nguyen, Thanh Hai/HLG-9900-2023 ⓘ 57189037439; 56010668800; 55768214700; 57215006315; 56214793100; 37106939800 ⓘ kimjy@gnu.ac.kr; ⓘ PLANT PHYSIOLOGY ⓘ PLANT PHYSIOL ⓘ 0032-0889 1532-2548 184 1 SCIE PLANT SCIENCES ⓘ 2020 8.34 3.6 1.11 2025-06-25 ⓘ 21 20 ⓘ SPHINGOSINE KINASE; GLUCOSYLCERAMIDE BIOSYNTHESIS; ACID SPHINGOMYELINASE; PLANT SPHINGOLIPIDS; IMMUNE-RESPONSES; PHOSPHOLIPASE-C; MEMBRANE RAFTS; NITRIC-OXIDE; GUARD-CELLS; GPI-ANCHOR ⓘ ⓘ ⓘ English 2020 2020-09 10.1104/pp.20.00401 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ New Era of Air Quality Monitoring from Space: Geostationary Environment Monitoring Spectrometer (GEMS) ⓘ The Geostationary Environment Monitoring Spectrometer (GEMS) is scheduled for launch in February 2020 to monitor air quality (AQ) at an unprecedented spatial and temporal resolution from a geostationary Earth orbit (GEO) for the first time. With the development of UV-visible spectrometers at sub-nm spectral resolution and sophisticated retrieval algorithms, estimates of the column amounts of atmospheric pollutants (O-3, NO2, SO2, HCHO, CHOCHO, and aerosols) can be obtained. To date, all the UV-visible satellite missions monitoring air quality have been in low Earth orbit (LEO), allowing one to two observations per day. With UV-visible instruments on GEO platforms, the diurnal variations of these pollutants can now be determined. Details of the GEMS mission are presented, including instrumentation, scientific algorithms, predicted performance, and applications for air quality forecasts through data assimilation. GEMS will be on board the Geostationary Korea Multi-Purpose Satellite 2 (GEO-KOMPSAT-2) satellite series, which also hosts the Advanced Meteorological Imager (AMI) and Geostationary Ocean Color Imager 2 (GOCI-2). These three instruments will provide synergistic science products to better understand air quality, meteorology, the long-range transport of air pollutants, emission source distributions, and chemical processes. Faster sampling rates at higher spatial resolution will increase the probability of finding cloud-free pixels, leading to more observations of aerosols and trace gases than is possible from LEO.

○ ○ Review ⓘ Unknown to Known: Advancing Knowledge of Coral Gene Function ⓘ Given the catastrophic changes befalling coral reefs, understanding coral gene function is essential to advance reef conservation. This has proved challenging due to the paucity of genomic data and genetic tools available for corals. Recently CRISPR/Cas9 gene editing was applied to these species; however, a major bottleneck is the identification and prioritization of candidate genes for manipulation. This issue is exacerbated by the many unknown ('dark') coral genes that may play key roles in the stress response. We review the use of gene coexpression networks that incorporate both known and unknown genes to identify targets for reverse genetic analysis. This approach also provides a framework for the annotation of dark genes in established inter action networks to improve our fundamental knowledge of coral gene function. ⓘ Cleves, Phillip A.; Shumaker, Alexander; Lee, Junmo; Putnam, Hollie M.; Bhattacharya, Debashish ⓘ Stanford Univ, Dept Genet, Stanford, CA 94305 USA; Rutgers State Univ, Microbial Biol Grad Program, New Brunswick, NJ 08901 USA; Rutgers State Univ, Dept Biochem & Microbiol, New Brunswick, NJ 08901 USA; Univ Rhode Isl, Dept Biol Sci, Kingston, RI 02881 USA; Kyungpook Natl Univ, Dept Oceanog, Daegu 41566, South Korea ⓘ Putnam, Hollie/AFJ-8174-2022 ⓘ 56148455400; 57191609433; 57217851052; 25621868600; 7201931909 ⓘ d.bhattacharya@rutgers.edu; ⓘ TRENDS IN GENETICS ⓘ TRENDS GENET ⓘ 0168-9525 1362-4555 36 2 SCIE GENETICS & HEREDITY ⓘ 2020 11.639 3.7 0.84 2025-06-25 ⓘ 33 31 ⓘ CLIMATE-CHANGE; HEAT-STRESS; GENOME; RESILIENCE; RESISTANCE; RESPONSES; DNA; METHYLATION; EXPRESSION; MODEL ⓘ coexpression network; coral bleaching; genome editing; multiomics; thermal stress ⓘ Animals; Anthozoa; Coral Reefs; Gene Editing; Genome; Genomics; Phenotype; bleaching; coral reef; CRISPR-CAS9 system; gene editing; gene function; genetic analysis; review; temperature stress; animal; Anthozoa; coral reef; gene editing; genetics; genome; genomics; phenotype ⓘ English 2020 2020-02 10.1016/j.tig.2019.11.001 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Effect of technological developments for smartphone lithium battery on metal-derived resource depletion and toxicity potentials ⓘ Smartphone technology development has led to a phenomenal increase in its use worldwide, triggering the development of efficient and safe lithium batteries to support advanced smartphones. Lithium ion batteries have many advantages such as high energy density, long lifetime, small size, low weight, no memory effect, and a slow loss of energy. Since new lithium batteries have been continually developed along with new smartphones, the batteries have high potentials to incur environmental impacts associated with rare, precious, and toxic metals. Thus, this study evaluates and compares metal-derived environmental impact potentials from smartphone lithium batteries taking into account battery model replacements, in order to figure out the environmental effect of battery technology development. The concentrations of metals in the batteries were analyzed to determine whether the batteries would be classified as hazardous waste. Life cycle impact assessment methods are used to evaluate resource depletion, human health toxicity, and eco-toxicity potentials from metals. The results showed that the technological development of the batteries did not contribute to reducing hazardous waste potentials. However, it significantly decreased resource depletion and toxicity potentials because the masses of metals were overall reduced over the battery model replacements. This study can be used to provide environmental information for manufacturers to produce low-impact lithium batteries and for e-waste policy makers to effectively manage and recover hazardous and toxic metals in waste batteries. ⓘ Mejame, Palle Paul Mejame; Jung, Da-Yoon; Lee, Heesoo; Lee, Dae Sung; Lim, Seong-Rin ⓘ Kangwon Natl Univ, Coll Engn, Dept Environm Engn, Chunchon 24341, Gangwon, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea ⓘ ⓘ 57191475998; 57215585506; 57215582338; 55568524907; 14626162700 ⓘ daesung@knu.ac.kr;srlim@kangwon.ac.kr; ⓘ RESOURCES CONSERVATION AND RECYCLING ⓘ RESOUR CONSERV RECY ⓘ 0921-3449 1879-0658 158 SCIE ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES ⓘ 2020 10.204 3.8 1.07 2025-06-25 ⓘ 22 29 ⓘ LIFE-CYCLE ASSESSMENT; ION BATTERIES; SEPARATION; RECOVERY; ENERGY; COBALT; IMPACT ⓘ ⓘ Battery management systems; Electronic Waste; Environmental impact; Environmental technology; Hazards; Life cycle; Metals; Natural resources; Smartphones; Toxicity; antimony; barium; beryllium; chromium; cobalt; copper; lead; lithium; nickel; selenium; silver; zinc; Battery technology; Environmental information; High energy densities; Life cycle impact assessment; Resource depletion; Technological development; Technology development; Toxicity potential; electronic waste; hazardous waste; heavy metal; technological development; toxicity; Article; concentration (parameter); controlled study; e-waste; ecotoxicity; environmental impact; hazardous waste; health hazard; industry; life cycle assessment; policy; resource depletion; technology; waste management; Lithium-ion batteries ⓘ English 2020 2020-07 10.1016/j.resconrec.2020.104797 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Effective Indoor Coverage via Radio-Over-Cable Fronthauls: Analog Fronthauls Come of Age ⓘ This article considers a radio-over-cable (RoC)based analog link on a local area network (LAN) cable [e.g., category (CAT) 5] as the last hop of the fronthaul for indoor mobile service coverage. We first present state-of-the-art mobile systems with RoC-based fronthauls and then discuss a number of critical issues regarding real implementation. These issues include the function module, called the radio-cable access unit (RCU), that interfaces with the radio frequency (RF) and intermediate frequency (IF) signals along the LAN cable as well as the design of an RF front end (RF-FE) that supports time-division duplex (TDD) and frequency-division duplex (FDD) modes. Then, the proposed nonconfigurable distributed antenna unit (NC-DAU) and corresponding resource-mapping scheme [NC air-tocable (NC-A2C)] are introduced, aiming to achieve lowcost, large-scale indoor deployment. We examine the performance of the NC-A2C and compare it with the optimal case. ⓘ Naqvi, Syed Hassan Raza; Ho, Pin-Han; Peng, Limei ⓘ Univ Waterloo, Dept Elect & Comp Engn, Waterloo, ON, Canada; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea ⓘ ⓘ 56810511600; 7402211578; 7201574271 ⓘ shrnaqvi@uwaterloo.ca;p4ho@uwaterloo.ca;auroraplm@knu.ac.kr; ⓘ IEEE VEHICULAR TECHNOLOGY MAGAZINE ⓘ IEEE VEH TECHNOL MAG ⓘ 1556-6072 1556-6080 15 2 SCIE ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;TRANSPORTATION SCIENCE & TECHNOLOGY ⓘ 2020 10.384 3.8 0.08 2025-06-25 ⓘ 0 1 Optical fiber cables; Antennas; Local area networks; Power cables; Optical fibers; Communication cables; Digital-analog conversion ⓘ ⓘ ⓘ Antennas; Cables; Distributed antennas; Frequency-division duplexes; Intermediate frequency signals; Local area networks (LAN); Radio frequencies; Resource mapping; State of the art; Time division duplex; Local area networks ⓘ English 2020 2020-06 10.1109/mvt.2020.2979265 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Genetic mapping of the c1 locus by GBS-based BSA-seq revealed Pseudo-Response Regulator 2 as a candidate gene controlling pepper fruit color ⓘ Key message The Pseudo-Response Regulator 2 gene was identified in the c1 locus, representing a genetic factor regulating fruit color in pepper using GBS-based BSA-seq. The loci c1, c2, and y have been widely reported as genetic determinants of various ripe fruit colors in pepper. However, c1, which may impact reduced pigmentation in red, orange, and yellow fruits, is not well understood. Two cultivars showing peach or orange fruit in Capsicum chinense 'Habanero' were found to have c2 mutation and were hypothesized to segregate c1 locus in the F-2 population. Habanero peach (HP) showed a reduced level of chlorophylls, carotenoids and total soluble solids in immature and ripe fruits. A microscopic examination of the fruit pericarps revealed smaller plastids and less stacked thylakoid grana in HP. The expression of many genes related to chlorophyll and carotenoid biosynthetic pathways were reduced in HP. To identify the genomic region of the c1 locus, bulked segregant analysis combined with genotyping-by-sequencing was employed on an F-2 population derived from a cross between Habanero orange and HP. One SNP at chromosome 1 was strongly associated with the peach fruit color. Pepper Pseudo-Response Regulator 2 (PRR2) was located close to the SNP and cosegregated with the peach fruit color. A 41 bp deletion at the third exon-intron junction region of CcPRR2 in HP resulted in a premature termination codon. A nonsense mutation of CaPRR2 was found in C. annuum 'IT158782' which had white ripe fruit coupled with null mutations of capsanthin-capsorubin synthase (y) and phytoene synthase 1 (c2). These results will be useful for the genetic improvement in fruit color and nutritional quality in pepper. ⓘ Lee, Soo Bin; Kim, Jeong Eun; Kim, Hyoung Tae; Lee, Gyu-Myung; Kim, Byung-Soo; Lee, Je Min ⓘ Kyungpook Natl Univ, Dept Hort Sci, Coll Agr & Life Sci, BK21 Plus Program, Daegu 41566, South Korea ⓘ Lee, Je Min/F-9797-2014; Lee, Je/AAE-7496-2020 ⓘ 57215038599; 57200327191; 56181017100; 57194456311; 57202440197; 8885729900 ⓘ jemin@knu.ac.kr; ⓘ THEORETICAL AND APPLIED GENETICS ⓘ THEOR APPL GENET ⓘ 0040-5752 1432-2242 133 6 SCIE AGRONOMY;GENETICS & HEREDITY;HORTICULTURE;PLANT SCIENCES ⓘ 2020 5.699 3.8 2.08 2025-06-25 ⓘ 43 43 ⓘ CAPSANTHIN-CAPSORUBIN SYNTHASE; DISEASE-RESISTANCE GENES; CAROTENOID METABOLISM; PHYTOENE SYNTHASE; SIGNAL-TRANSDUCTION; PROVIDES INSIGHTS; Y LOCUS; TOMATO; CAPSICUM; MUTANT ⓘ ⓘ Capsicum; Chromosome Mapping; Color; Fruit; Genes, Plant; Genotype; Models, Genetic; Pigmentation; Plant Proteins; Plastids; Polymorphism, Single Nucleotide; Chlorophyll; Citrus fruits; Genes; Pigments; Plants (botany); plant protein; Biosynthetic pathway; Bulked segregant analysis; Genetic improvements; Nutritional qualities; Phytoene synthase; Premature termination codon; PSEUDO-RESPONSE REGULATOR; Total soluble solids; biological model; chromosomal mapping; color; fruit; genetics; genotype; pepper; physiology; pigmentation; plant gene; plastid; single nucleotide polymorphism; Color ⓘ English 2020 2020-06 10.1007/s00122-020-03565-5 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Review ⓘ Influence of particle size on the effective thermal conductivity of nanofluids: A critical review ⓘ Nanofluid is an innovative class of nanotechnology-based thermal fluids and has been proven to improve the energy conversion process efficiency significantly. Thermal conductivity of the nanofluids, the fundamental thermophysical property determining their performance, is a subject of extensive controversies over the years and thereby incites the fundamental doubts in the commercial application of these innovative thermal fluids. A possible justification of these inconsistencies is the lack of comprehensive data over a wide range of sensitive parameters characterizing the effective thermal conductivity of the nanofluids including particle morphology (size and shape) and concentration, fluid temperature, particle and hosting fluid properties, measurement and stability techniques. Particle size, the most discernible feature differentiating nanofluids from micrometre-sized suspensions, contributes not only in ensuring dispersion stability but predominantly influences their heat transport characteristics. Therefore the study is aimed at presenting a critical review of all the experimental, theoretical and numerical investigations on the particle-size-dependent effective thermal conductivity of the nanofluids to comprehend the influence of nanoparticle size variation on the thermal performance of the nanofluids in diverse nanofluid combinations and operational conditions. The study also incorporates a systematic comparison of the experimental results to explicate anomalies in reported results and the mutual impact of imperative parameters on the particle-size-dependent thermal conductivity of the nanofluids. ⓘ Ambreen, Tehmina; Kim, Man-Hoe ⓘ Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, IEDT, Daegu 41566, South Korea ⓘ ⓘ 57195420431; 55686310000 ⓘ manhoe.kim@knu.ac.kr; ⓘ APPLIED ENERGY ⓘ APPL ENERG ⓘ 0306-2619 1872-9118 264 SCIE ENERGY & FUELS;ENGINEERING, CHEMICAL ⓘ 2020 9.746 3.8 3.06 2025-06-25 ⓘ 177 196 Nanofluid; Nanoparticle size; Effective thermal conductivity; Energy efficiency ⓘ HEAT-TRANSFER CHARACTERISTICS; METAL-OXIDES/WATER NANOFLUIDS; SOLAR COLLECTOR; TROUGH COLLECTOR; ENTROPY GENERATION; BROWNIAN-MOTION; PRESSURE-DROP; TRANSFER ENHANCEMENT; ENERGY EXTRACTION; CARBON NANOTUBES ⓘ Effective thermal conductivity; Energy efficiency; Nanofluid; Nanoparticle size ⓘ Energy conversion; Energy efficiency; Nanofluidics; Nanoparticles; Particle size; Suspensions (fluids); Thermodynamic properties; Commercial applications; Dispersion stability; Effective thermal conductivity; Nanofluids; Nanoparticle sizes; Numerical investigations; Operational conditions; Particle morphologies; concentration (composition); efficiency measurement; energy efficiency; experimental study; nanoparticle; nanotechnology; particle size; performance assessment; Thermal conductivity of liquids ⓘ English 2020 2020-04-15 10.1016/j.apenergy.2020.114684 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Molecular-assisted breeding for improved carbohydrate profiles in soybean seed ⓘ Key message Two independent variant raffinose synthase 3 (RS3) alleles produced an equivalent phenotype and implicated the gene as a key contributor to soybean seed carbohydrate phenotype. Soybean is an important crop because the processed seed is utilized as a vegetable oil and a high protein meal typically used in livestock feeds. Raffinose and stachyose, the raffinose family of oligosaccharides (RFO) carbohydrate components of the seed, are synthesized in developing soybean seeds from sucrose and galactinol. Sucrose is considered positive for metabolizable energy, while RFO are anti-nutritional factors in diets of monogastric animals such as humans, poultry, and swine. To increase metabolizable energy available in soybean seed meal, prior research has been successful in deploying variant alleles of key soybean raffinose synthase (RS) genes leading to reductions or near elimination of seed RFO, with significant increases in seed sucrose. The objective of this research was to investigate the specific role of variants of the RS3 gene in a genomic context and improve molecular marker-assisted selection for the ultra-low (UL) RFO phenotype in soybean seeds. The results revealed a new variant of the RS3 allele (rs3 snp5, rs3 snp6) contributed to the UL RFO phenotype when mutant alleles of RS2 were present. The variant RS3 allele identified was present in about 15% of a small set of soybean cultivars released in North America. A missense allele of the RS3 gene (rs3 G75E) also produced the UL RFO phenotype when combined with mutant alleles of RS2. The discoveries reported here enable direct marker-assisted selection for an improved soybean meal trait that has the potential to add value to soybean by improving the metabolizable energy of the meal. ⓘ Hagely, Katherine B.; Jo, Hyun; Kim, Jeong-Hwa; Hudson, Karen A.; Bilyeu, Kristin ⓘ Univ Missouri, Div Plant Sci, 110 Waters Hall, Columbia, MO 65211 USA; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Purdue Univ, USDA ARS, Crop Prod & Pest Control Res Unit, 915 West State St,Lilly Hall, W Lafayette, IN 47907 USA; Univ Missouri, USDA ARS, Plant Genet Res Unit, 110 Waters Hall, Columbia, MO 65211 USA ⓘ ⓘ 26638855000; 57194539358; 57033187400; 36016812800; 6603201770 ⓘ HagelyKB@missouri.edu;johyun@knu.ac.kr;jk3zb@mail.missouri.edu;Karen.Hudson@usda.gov;Kristin.Bilyeu@usda.gov; ⓘ THEORETICAL AND APPLIED GENETICS ⓘ THEOR APPL GENET ⓘ 0040-5752 1432-2242 133 4 SCIE AGRONOMY;GENETICS & HEREDITY;HORTICULTURE;PLANT SCIENCES ⓘ 2020 5.699 3.8 1.44 2025-06-25 ⓘ 24 28 ⓘ RAFFINOSE FAMILY OLIGOSACCHARIDES; ENVIRONMENTAL STABILITY; METABOLIZABLE ENERGY; REGISTRATION; DIVERSITY; MATURITY; APPARENT; ALLELES; SUGARS; WILD ⓘ ⓘ Alleles; Carbohydrate Metabolism; Carbohydrates; DNA Shuffling; Ecotype; Genes, Plant; Haplotypes; Mutation; Polymorphism, Single Nucleotide; Reverse Genetics; Seeds; Soybeans; Agriculture; Genes; Nutrition; Sugar (sucrose); carbohydrate; Anti-nutritional factors; Livestock feed; Marker-assisted selection; Metabolizable energies; Molecular marker; Monogastric animals; Mutant alleles; Raffinose synthase; allele; carbohydrate metabolism; DNA shuffling; ecotype; genetics; haplotype; metabolism; mutation; plant gene; plant seed; reverse genetics; single nucleotide polymorphism; soybean; Soybean oil ⓘ English 2020 2020-04 10.1007/s00122-020-03541-z ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Multi-objective home appliance scheduling with implicit and interactive user satisfaction modelling ⓘ Residential consumers desire to minimize electricity bills while maximizing comfort by appropriate appliance scheduling. The conflicting nature of the objectives facilitates a multi-objective formulation that can provide a set of tradeoff schedules enabling better decision making. In literature, user preference or comfort regarding each device at each time instance is obtained explicitly. In addition, scheduling interval of 1-hour is considered because reducing scheduling interval to 1 or 5 min drastically increases - (1) the dimensionality of search space and complicates the search process, and (2) the number of time instances for which the user has to explicitly provide the preference resulting in human fatigue. However, it is essential to schedule the devices at lower scheduling intervals to precisely-estimate the electricity consumption due to the presence of high power devices such as microwave that operate for shorter intervals (< 5 min). In this work, we employ an efficient and scalable multi-objective evolutionary algorithm to solve the scheduling problem. In addition, the user preference is implicitly estimated from the past usage patterns obtained using energy disaggregation. And, if the estimated user preference deviates from the user expectation then the user can modify preference using weights referred to as priority weights. The novel implicit user satisfaction modeling and interactive customization through priority weights makes the proposed work a standalone approach suitable for any user. Experimental results and analysis for various user priorities and scheduling intervals (ranging from 1-minute to 1-hour) proves that the proposed framework is able to provide generalized schedules. ⓘ Pamulapati, Trinadh; Mallipeddi, Rammohan; Lee, Minho ⓘ Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea ⓘ Pamulapati, Trinadh Reddy/AAC-5277-2021; Mallipeddi, Rammohan/AAL-5306-2020 ⓘ 57195281873; 25639919900; 57191730119 ⓘ mallipeddi.ram@gmail.com; ⓘ APPLIED ENERGY ⓘ APPL ENERG ⓘ 0306-2619 1872-9118 267 SCIE ENERGY & FUELS;ENGINEERING, CHEMICAL ⓘ 2020 9.746 3.8 1.48 2025-06-25 ⓘ 27 31 Multi-objective scheduling; Home appliance scheduling; Electricity cost minimization; Implicit user satisfaction estimation; Interactive scheduling; Energy disaggregation ⓘ EVOLUTIONARY ALGORITHMS; ENERGY-CONSUMPTION; DEMAND RESPONSE; THERMAL COMFORT; OPEN PLAN; MANAGEMENT; BUILDINGS; MOVEMENT ⓘ Electricity cost minimization; Energy disaggregation; Home appliance scheduling; Implicit user satisfaction estimation; Interactive scheduling; Multi-objective scheduling ⓘ Decision making; Domestic appliances; Economic and social effects; Evolutionary algorithms; Electricity-consumption; High-power devices; Multi objective evolutionary algorithms; Multi-objective formulation; Residential consumers; Scheduling interval; Scheduling problem; User expectations; equipment; experimental study; literature review; numerical model; trade-off; Scheduling ⓘ English 2020 2020-06-01 10.1016/j.apenergy.2020.114690 ⓘ 바로가기 바로가기 바로가기 바로가기
