| 2 | Microbial community structure in an integrated A/O reactor treating diluted livestock wastewater during start-up period显示文摘In order to investigate the correlation between reactor performance and the microorganisms,an integrated A/O reactor was operated for 72 days to treat diluted livestock wastewater.Chemical oxygen demand (COD) removal efficiency increased from 79% to 94%,with total nitrogen (TN) removal efficiency from 37% to 50% (HRT 7.4 hr) when the influent COD and TN were ca.1500 mg/L and 95 mg/L,respectively,and the outlet COD concentration was less than 100 mg/L at the end.Microbial community was monitored during start-up period by denaturing gradient gel electrophoresis (DGGE) based on 16S rRNA gene.DGGE profiles showed that microbial community had changed significantly during the start-up and these shifts were in accordance with the reactor performance.UPGMA clustering analysis showed that 14 anaerobic samples fell into five main groups and so did the aerobic ones,but the grouping patterns were different.Phylogenetic analysis indicated that microbial populations in the anaerobic compartment belonged to Firmicutes,Proteobacteria,Chloroflexi and Bacteroidetes,while Proteobacteria,Bacteroidetes,Firmicutes,Verrucomicrobiae and Nitrospira were present in the aerobic compartment.In the anaerobic compartment,more fermentative and acetogenic bacteria were detected during the start-up while denitrifying bacteria faded away.Two functional populations such as Nitrospira defluvii and Dechloromonas denitrificans were observed when nitrogen removal was high,indicating that simultaneous nitrification and denitrification occurred in the aerobic compartment. | Lijiao Ren,Yining Wu,Nanqi Ren,Kun Zhang,Defeng Xing State Key Laboratory of Urban Water Resource and Environment,Harbin Institute of Technology,Harbin 150090,China. | 2010 | Journal of Environmental Sciences2010，22，5： | 14 |
| 3 | Monitoring of microbial community structure and succession in the biohydrogen production reactor by denaturing gradient gel electrophoresis(DGGE)显示文摘To study the structure of microbial communities in the biological hydrogen produc- tion reactor and determine the ecological function of hydrogen producing bacteria, anaerobic sludge was obtained from the continuous stirred tank reactor (CSTR) in different periods of time, and the diversity and dynamics of microbial communities were investigated by denaturing gra- dient gel electrophoresis (DGGE). The results of DGGE demonstrated that an obvious shift of microbial population happened from the beginning of star-up to the 28th day, and the ethanol type fermentation was established. After 28 days the structure of microbial community became stable, and the climax community was formed. Comparative analysis of 16S rDNA sequences from reamplifying and sequencing the prominent bands indicated that the dominant population belonged to low G+C Gram-positive bacteria (Clostridium sp. and Ethanologenbacterium sp.), β- proteobacteria (Acidovorax sp.), γ-proteobacteria (Kluyvera sp.), Bacteroides (uncultured bacte- rium SJA-168), and Spirochaetes (uncultured eubacterium E1-K13), respectively. The hydrogen production rate increased obviously with the increase of Ethanologenbacterium sp., Clostridium sp. and uncultured Spirochaetes after 21 days, meanwhile the succession of ethanol type fer- mentation was formed. Throughout the succession the microbial diversity increased however it decreased after 21 days. Some types of Clostridium sp. Acidovorax sp., Kluyvera sp., and Bac- teroides were dominant populations during all periods of time. These special populations were essential for the construction of climax community. Hydrogen production efficiency was de- pendent on both hydrogen producing bacteria and other populations. It implied that the co- metabolism of microbial community played a great role of biohydrogen production in the reactors. | XING Defeng REN Nanqi GONG Manli LI Jianzheng LI Qiubo | 2005 | Science China(Life Sciences)2005，48，2： | 5 |
| 4 | Quorum sensing systems regulate heterotrophic nitrification-aerobic denitrification by changing the activity of nitrogen-cycling enzymes显示文摘Heterotrophic nitrification-aerobic denitrification(HNAD)is essential in diverse nitrogen-transforming processes.How HNAD is modulated by quorum sensing(QS)systems is still ambiguous.The QS system in Pseudomonas aeruginosa manipulates colony behavior.Here,we described the influence of the Pseudomonas quinolone signal(PQS)and N-acyl-L-homoserine lactone(AHL)on HNAD.The HNAD of P.aeruginosa was inhibited by the oversecretion of PQS.AHL-or PQS-deficient P.aeruginosa mutants had a higher ability for nitrogen removal.QS inhibited heterotrophic nitrification mainly via controlling the activity of nitrite oxidoreductase(NXR)and the depressed aerobic denitrification by regulating the catalytic abilities of nitric oxide reductase(NOR),nitrite reductase(NIR),and nitrate reductase(NAR).The addition of citrate as the sole carbon source increased the nitrogen removal efficiency compared with other carbon sources.Nitrite,as the sole nitrogen source,could be used entirely with only the moderate concentration of PQS contained.AHL and PQS controlled both nitrification and denitrification,suggesting that QS plays an important role in nitrogen cycle under aerobic conditions. | Ziqian Zhu Yang Yang Anran Fang Yu Lou Guojun Xie Nanqi Ren Defeng Xing | 2020 | Environmental Science and Ecotechnology2020，，2： | 2 |

| 15 | Shipboard bilge water treatment by electrocoagulation powered by microbial fuel cells显示文摘Ships generate large amounts of wastewater including oily bilge water, blackwater and greywater. Traditionally they are treated separately with high energy consumption. In this study we demonstrate the feasibility that these waste streams can be treated using an integrated electrocoagulation cell (ECC) and microbial fuel cell (MFC) process, which not only synergized the contaminants removal but also accomplished energy neutrality by directly powering EC with MFC electricity. Results showed that MFC stack powered ECC removed 93% of oily organics, which is comparable to the performance of an external DC voltage powered ECC. In the meantime, more than 80% of COD was removed from MFCs when fed with either acetate or municipal wastewater. Moreover, the ECC electrode area and distance showed notable effects on current generation and contaminants removal, and further studies should focus on operation optimization to enhance treatment efficiency. | Xiaoxue Mei Heming Wang Dianxun Hou Fernanda Leite Lobo Defeng Xing Zhiyong Jason Ren | 2019 | Frontiers of Environmental Science & Engineering2019，13，4： | 0 |
| 16 | Neural networks modeling signal responses and taxol production of cultured Taxus chinensis cells induced by bio-elicitor显示文摘Quantitatively describing the signal transduction process is important for understanding the mechanism of signal regulation in cells,and thus,poses both a challenge and an opportunity for chemical and biochemical engineers.An artificial neural network(ANN),in which we took the signal molecules as neural nodes,was constructed to simulate the generation of active oxygen species(AOS)in Taxus chinensis cells induced by a bio-elicitor.The relative contents of AOS in cells predicted by the ANN model agreed well with the experimental data and three notable stages of AOS increase were observed from the 3D figure of AOS generation.The robustness of AOS trajectories indicated that signal regula-tion in vivo was an integral feedback control model that ensured the adaptation of Taxus chinensis to environmental stress.The artificial neural network was able to predict taxol production as well as determine the optimal concentration of oligosaccharides needed for it. | GONG Yanwen REN Defeng YUAN Yingjin | 2007 | Frontiers of Chemical Science and Engineering2007，1，2： | 0 |
