| 1 | Effect of Trichoderma viride biofertilizer on ammonia volatilization from an alkaline soil in Northern China显示文摘Ammonia(NH3) volatilization is one of the primary pathways of nitrogen(N) loss from soils after chemical fertilizer is applied, especially from the alkaline soils in Northern China, which results in lower efficiency for chemical fertilizers. Therefore, we conducted an incubation experiment using an alkaline soil from Tianjin(p H 8.37–8.43) to evaluate the suppression effect of Trichoderma viride(T. viride) biofertilizer on NH3 volatilization, and compared the differences in microbial community structure among all samples. The results showed that viable T. viride biofertilizer(T) decreased NH_3 volatilization by 42.21% compared with conventional fertilizer((CK), urea), while nonviable T. viride biofertilizer(TS) decreased NH_3 volatilization by 32.42%. NH_3 volatilization was significantly higher in CK and sweet potato starch wastewater(SPSW) treatments during the peak period. T. viride biofertilizer also improved the transfer of ammonium from soil to sweet sorghum. Plant dry weights increased 91.23% and 61.08% for T and TS, respectively, compared to CK. Moreover, T. viride biofertilizer enhanced nitrification by increasing the abundance of ammonium-oxidizing archaea(AOA) and ammonium-oxidizing bacteria(AOB). The results of high-throughput sequencing indicated that the microbial community structure and composition were significantly changed by the application of T. viride biofertilizer. This study demonstrated the immense potential of T. viride biofertilizer in reducing NH_3 volatilization from alkaline soil and simultaneously improving the utilization of fertilizer N by sweet sorghum. | Xia Wang Shengjun Xu Shanghua Wu Shugeng Feng Zhihui Bai Guoqiang Zhuang Xuliang Zhuang | 2018 | Journal of Environmental Sciences2018，30，4： | 15 |
| 2 | Haze insights and mitigation in China: An overview显示文摘The present article provides an overview of the chemical and physical features of haze in China, focusing on the relationship between haze and atmospheric fine particles, and the formation mechanism of haze. It also summarizes several of control technologies and strategies to mitigate the occurrence of haze. The development of instruments and the analysis of measurements of ambient particles and precursor concentrations have provided important information about haze formation. Indeed, the use of new instruments has greatly facilitated current haze research in China. Examples of insightful results include the relationship between fine particles and haze, the chemical compositions and sources of particles, the impacts of the aging process on haze formation, and the application of technologies that control the formation of haze. Based on these results, two relevant issues need to be addressed: understanding the relationship between haze and fine particles and understanding how to control PM2.5. | Xuliang Zhuang Yuesi Wang Hong He Jianguo Liu Xinming Wang Tingyu Zhu Maofa Ge Ju Zhou Guiqian Tang Jinzhu Ma | 2014 | Journal of Environmental Sciences2014，26，1： | 12 |
| 3 | Long-and short-chain AHLs affect AOA and AOB microbial community composition and ammonia oxidation rate in activated sludge显示文摘Quorum sensing(QS)regulation of the composition of ammonia-oxidising archaea(AOA)and ammonia-oxidising bacteria(AOB)communities and functions in wastewater treatment was investigated.Specifically,we explored the role of N-acyl-L-homoserine lactones(AHLs)in microbial community dynamics in activated sludge.On average,the specific ammoniaoxidising-rate increased from 1.6 to 2.8 mg NH_4^+-N/g MLSS/hr after treatment with long-chain AHLs for 16 days,and the addition of AHLs to sludge resulted in an increased number of AOA/AOB amoA genes.Significant differences were observed in the AOA communities of control and AHL-treated cultures,but not the AOB community.Furthermore,the dominant functional AOA strains of the Crenarchaeota altered their ecological niche in response to AHL addition.These results provide evidence that AHLs play an important role in mediating AOA/AOB microbial community parameters and demonstrate the potential for application of QS to the regulation of nitrogen compound metabolism in wastewater treatment. | Jie Gao Yu Duan Ying Liu Xuliang Zhuang Yichen Liu Zhihui Bai Wenlin Ma Guoqiang Zhuang | 2019 | Journal of Environmental Sciences2019，31，4： | 11 |
| 4 | Substrate-induced changes in microbial community-level physiological profiles and their application to discriminate soil microbial communities显示文摘The addition of simple substrates could affect the microbial respiration in soils. This substrate-induced respiration is widely used to estimate the soil microbial biomass, but little attention has been paid to its influence on the changes of community-level physiological profiles. In this study, the process of microbial communities responding to the added substrate using sole-carbon-source utilization (BIOLOG) was investigated. BIOLOG is biased toward fast-growing bacteria; this advantage was taken to detect the prompt response of the active microbial communities to the added substrate. Four soil samples from agricultural fields adjacent to heavy metal mines were amended with L-arginine, citric acid, or D-glucose. Substrate amendments could, generally, not only increase the metabolic activity of the microbial communities, but also change the metabolic diverse patterns compared with no-substrate control. By tracking the process, it was found that the variance between substrate-induced treatment and control fluctuated greatly during the incubation course, and the influences of these three substrates were different. In addition, the application of these induced changes to discriminate soil microbial communities was tested. The distance among all samples was greatly increased, which further showed the functional variance among microbial communities in soils. This can be very useful in the discrimination of microbial communities even with high similarity. | CHEN Jian XIE Huijun ZHUANG Xuliang ZHUANG Guoqiang BAI Zhihui ZHANG Hongxun | 2008 | Journal of Environmental Sciences2008，20，6： | 10 |
| 5 | Performance and recent improvement in microbial fuel cells for simultaneous carbon and nitrogen removal: A review显示文摘Microbial fuel cells(MFCs) have become a promising technology for wastewater treatment accompanying electricity generation. Carbon and nitrogen removal can be achieved by utilizing the electron transfer between the anode and cathode in an MFC. However,large-scale power production and high removal efficiency must be achieved at a low cost to make MFCs practical and economically competitive in the future. This article reviews the principles, feasibility and bottlenecks of MFCs for simultaneous carbon and nitrogen removal, the recent advances and prospective strategies for performance improvement, as well as the involved microbes and electron transfer mechanisms. | Haishu Sun Shengjun Xu Guoqiang Zhuang Xuliang Zhuang | 2016 | Journal of Environmental Sciences2016，28，1： | 10 |
| 6 | Effects of exogenous short-chain N-acyl homoserine lactone on denitrifying process of Paracoccus denitrificans显示文摘N-acyl-homoserine lactones(AHLs) serve as quorum-sensing signals, which control a number of bacterial processes in many proteobacteria. Here we report the effects of exogenous short-chain AHL on the denitrifying process of Paracoccus denitrificans, which are capable of aerobic and anaerobic growth by utilizing nitrate. The denitrification activity of these cells was monitored by measuring denitrification products(including nitrate, nitrite,and nitrous oxide), and the individual messenger ribonucleic acid(m RNA) levels of nitrate,nitrite, nitric oxide and nitrous oxide reductases. The results indicated that 2 μmol/L C6-homoserine lactone(HSL) has little effect on cell density under either anaerobic or aerobic culture conditions, and the nitrate reduction activity appeared slightly affected by N-hexanoyl-DL-homoserine lactone(C6-HSL). However, exogenous C6-HSL significantly affected the transcription of nitrite reductase and nitric oxide reductase genes in P.denitrificans regardless of the presence of oxygen, and N_2O accumulation activity in P. denitrificans was suppressed by C6-HSL under aerobic condition. In contrast, exogenous C6-HSL stimulated the production of N_2O under anaerobic condition, suggesting that the regulation of denitrification by quorum sensing may be important in N_2O release. | Yun Cheng Yang Zhang Qiuxuan Shen Jie Gao Guoqiang Zhuang Xuliang Zhuang | 2017 | Journal of Environmental Sciences2017，29，4： | 6 |
| 7 | In situ enhanced bioremediation of dichlorvos by a phyllosphere Flavobacterium strain显示文摘A bacterium capable of degrading dichlorvos was isolated from the rape phyllosphere and designated YD4. The strain was identified as Flavobacterium sp., based on its phenotypic features and 16S rRNA gene sequence. Strain YD4 was able to utilize dichlorvos as the sole source of phosphorus. In situ enhanced bioremedia- tion of dichlorvos by YD4 was hereafter studied. Chlorpyrifos and phoxim could also be degraded by this strain as the sole phosphorus source. A higher degradation rate of dichlorvos was observed after spraying YD4 onto the surface of rape leaves when compared to the sterilized- YD4 and water-treated samples. The results indicated that pesticide-degrading epiphytic bacterium could become a new way for in situ phyllosphere bioremediation where the hostile niche is unsuitable for other pesticide-degrading bacteria isolated from soil and water. | Jiying NING Gang GANG Zhihui BAI Qing HU Hongyan QI Anzhou MA Xuliang ZHUAN Guoqiang ZHUANG | 2012 | Frontiers of Environmental Science & Engineering2012，6，2： | 2 |
| 8 | Investigating the bacterial community and amoebae population in rural domestic wastewater reclamation for irrigation显示文摘Reclamation of domestic wastewater for agricultural irrigation is viewed as a sustainable option to create an alternative water source and address water scarcity. Free-living amoebae(FLA), which are amphizoic protozoa, are widely distributed in various environmental sources. The FLA could cause considerable environmental and health risks. However, little information is available on the risk of these protozoa. In this study, we evaluated the feasibility using rural domestic wastewater for agricultural irrigation, and analyzed dynamic changes of the microbial community structure and FLA populations in raw and treated wastewater, as well as the phyllosphere and rhizosphere of lettuce production sites that were irrigated with different water sources. The bacterial community dynamics were analyzed by terminal restriction fragment length polymorphism(T-RFLP). The bacterial community structures in the influent were similar to that in the effluent, while in some cases relative abundances varied significantly. The populations of Acanthamoeba spp. and Hartmannella vermiformis in the anaerobically treated wastewater were significantly higher than in the raw wastewater. The vegetables could harbor diverse amoebae, and the abundances of Acanthamoeba spp. and H. vermiformis in the rhizosphere were significantly higher than in the phyllosphere. Accordingly, our studies show insight into the distribution and dissemination of amoebae in wastewater treatment and irrigation practices. | Bingjian Cui Jinxue Luo Decai Jin Bo Jin Xuliang Zhuang Zhihui Bai | 2018 | Journal of Environmental Sciences2018，30，8： | 2 |
| 9 | Microbial community structure analyses and cultivable denitrifier isolation of Myriophyllum aquaticum constructed wetland under low C/N ratio显示文摘With the rapid expansion of livestock production,the amount of livestock wastewater accumulated rapidly.Lack of biodegradable organic matter makes denitrification of livestock wastewater after anaerobic digestion more difficult.In this study,Myriophyllum aquaticum constructed wetlands(CWs)with efficient nitrogen removal performance were established under different carbon/nitrogen(C/N)ratios.Analysis of community composition reveals the change of M.aquaticum CWs in microbial community structure with C/N ratios.The proportion of Proteobacteria which is one of the dominant phyla among denitrifier communities increased significantly under low C/N ratio conditions.Besides,to obtain cultivable denitrifier that could be added into CWs in situ,33 strains belonging to phylum Proteobacteria were isolated from efficient M.aquaticum CWs,while the best-performing denitrification strain M3-1 was identified as Bacillus velezensis JT3-1(GenBank No.CP032506.1).Redundancy analysis and quadratic models showed that C/N ratio had significant effects on disposal of nitrate(NO_(3)^(−)-N)and the strains isolated could perform well in denitrification when C/N ratio is relatively low.In addition,they have relatively wide ranges of carbon sources,temperature and a high NO_(3)^(−)removal rate of 9.12 mg/(L·hr)at elevated concentrations of 800 mg/L nitrate.Thus,strains isolated from M.aquaticum CWs with low C/N ratio have a practical application value in the treatment of nitrate-containing wastewater.These denitrifying bacteria could be added to CWs to enhance nitrogen removal efficiency of CWs for livestock wastewater with low C/N ratio in the future. | Jialiang Zuo Lina Xu Jianlin Guo Shengjun Xu Shuanglong Ma Cancan Jiang Dongmin Yang Danhua Wang Xuliang Zhuang | 2023 | Journal of Environmental Sciences2023，，5： | 2 |
| 10 | Ecological selection of bacterial taxa with larger genome sizes in response to polycyclic aromatic hydrocarbons stress显示文摘Polycyclic aromatic hydrocarbons(PAHs)are ubiquitous priority pollutants that cause great damage to the natural environment and health.Average genome size in a community is critical for shedding light on microbiome's functional response to pollution stress within an environment.Here,microcosms under different concentrations were performed to evaluate the selection of PAHs stress on the average genome size in a community.We found the distinct communities of significantly larger genome size with the increase of PAHs concentration gradients in soils,and consistent trends were discovered in soils at different latitudes.The abundance of Proteobacteria and Deinococcus-Thermus with relatively larger genomes increased along with PAHs stress and well adapted to polluted environments.In contrast,the abundance of Patescibacteria with a highly streamlined and smaller genome decreased,implying complex interactions between environmental selection and functional fitness resulted in bacteria with larger genomes becoming more abundant.Moreover,we confirmed the increased capacity for horizontal transfer of degrading genes between communities by showing an increased connection number per node positively related to the nid A gene along the concentration gradients in the co-occurrence network.Our findings suggest PAHs tend to select bacterial taxa with larger genome sizes,with significant consequences for community stability and potential biodegradation strategies. | Yuzhu Dong Shanghua Wu Haonan Fan Xianglong Li Yijing Li Shengjun Xu Zhihui Bai Xuliang Zhuang | 2022 | Journal of Environmental Sciences2022，34，2： | 2 |

| 19 | Anaerobic degradation of xenobiotic organic contaminants(XOCs):The role of electron flow and potential enhancing strategies显示文摘In groundwater,deep soil layer,sediment,the widespread of xenobiotic organic contaminants(XOCs)have been leading to the concern of human health and eco-environment safety,which calls for a better understanding on the fate and remediation of XOCs in anoxic matrices.In the absence of oxygen,bacteria utilize various oxidized substances,e.g.nitrate,sulphate,metallic(hydr)oxides,humic substance,as terminal electron acceptors(TEAs)to fuel anaerobic XOCs degradation.Although there have been increasing anaerobic biodegradation studies focusing on species identification,degrading pathways,community dynamics,systematic reviews on the underlying mechanism of anaerobic contaminants removal from the perspective of electron flow are limited.In this review,we provide the insight on anaerobic biodegradation from electrons aspect-electron production,transport,and consumption.The mechanism of the coupling between TEAs reduction and pollutants degradation is deconstructed in the level of community,pure culture,and cellular biochemistry.Hereby,relevant strategies to promote anaerobic biodegradation are proposed for guiding to an efficient XOCs bioremediation. | Yijing Li Shanghua Wu Shijie Wang Shijie Zhao Xuliang Zhuang | 2021 | Journal of Environmental Sciences2021，33，3： | 1 |
| 20 | Construction of a dual fluorescence whole-cell biosensor to detect N-acyl homoserine lactones显示文摘Detection of N-acyl homoserine lactones(AHLs) is useful for understanding quorum sensing(QS) behaviors, including biofilm formation, virulence and metabolism. For detecting AHLs and indicating the host cells in situ, we constructed the plasmid pUCGMA2T1-4 to make a dual fluorescent wholecell biosensor based on the AhlI/R AHL system of Pseudomonas syringae pv. syringae B728a. The plasmid contains three components: constitutively expressed PnptII::gfp for indicating host cells, PahlI::mcherry that produces red fluorescence in response to AHL, and the ahlR gene that encodes an AHL regulatory protein. Meanwhile, two copies of T1-4(four tandem copies of a transcriptional terminator) were added into the plasmid to reduce background. The results showed that when the plasmid was placed into Escherichia coli, the dual fluorescence whole-cell biosensor was able to respond with red fluorescence within 6 hr to 5 × 10-8–1 × 10-5mol/L of 3OC6-HSL. Bright green fluorescence indicated the host cells. Furthermore, when the plasmid was transferred to wildtype Pseudomonas PhTA125(an AHL-producing bacterium), it also showed both green and red fluorescence. This result demonstrates that this plasmid can be used to construct whole-cell indicators that can indicate the AHL response and spatial behaviors of microbes in a microenvironmental niche. | Xuemei Deng Guoqiang Zhuang Anzhou Ma Qing Yu Xuliang Zhuang | 2014 | Journal of Environmental Sciences2014，26，2： | 1 |
