| 1 | Adsorption behavior of Azo Dye C. I. Acid Red 14 in aqueous solution on surface soils显示文摘Azo dyes have received considerable attention because of their association with various human health problems. The aim of the investigation is to determine the adsorption behavior of azo dyes in aqueous solution on DG06, GSE17200, and GSE17201 soils using C. I. Acid Red 14 (AR14) as example. The experimental results indicate that the Freundlich model expresses the adsorption isotherm better than the Langmuir model and the pseudo-second-order model achieves adsorption of AR14 on the three soils well. Based on the pseudo- second-order model, the adsorption thermodynamic of AR14 on DG06 soil have been studied and the thermodynamics parameter of ΔG0 is determined and ΔG0 value shows the adsorption process of AR14 on DG06 is mainly physical in nature. Furthermore, the effects of temperature, pH and salinity (NaCl) on adsorption have been investigated. The decrease in pH or the increase in salinity enhances the adsorption of AR14 by DG06, GSE17200, and GSE17201. | QU Baocheng ZHOU Jiti XIANG Xuemin ZHENG Chunli ZHAO Hongxia ZHOU Xiaobai | 2008 | Journal of Environmental Sciences2008，20，6： | 8 |
| 2 | Location and PCR analysis of catabolic genes in a novel Streptomyces sp. DUT_AHX capable of degrading nitrobenzene显示文摘A novel strain of Streptomyces sp.DUT_AHX was isolated from sludge contaminated with nitrobenzene and identified on the basis of physiological and biochemical tests and 16S ribosomal DNA (rDNA) sequence analysis.The optimal degradation conditions were as follows:temperature 30℃,pH 7.0-8.0,shaking speed 150-180 r/min,and inocula 10%(V/V).The strain,which possessed a partial reductive pathway with the release of ammonia,was also able to grow on mineral salts basal (MSB) medium plates with 2-aminophenol, ph... | Al Haixin Zhou Jiti Lv Hong Wang Jing Guo Hanb Liu Guangfei Qu Yuanyuan | 2008 | Journal of Environmental Sciences2008，20，7： | 7 |
| 3 | Decolorization of Anthraquinone dye by Rhodopseudomonas XL-1显示文摘Rhodopseudomonas XL 1 gained from textile wastewater can effectively decolorize anthraquinone dye. Under anaerobic condition, 93 percent of the anthraquinone dye is decolorized , which is higher than that under aerobic condition. The optimum pH is 6~9 and the optimum temperature is 20~40℃ for the anthraquinone dye decolorization by XL 1 . XL 1 can not decolorize the anthraquinone dye when it is the sole carbon source. Microbial cometabolism and decolorization of the dye take place in the presence of some other carbon source(0.2~0.4g/100ml)called cometabolic substrate. The cometabolic substrate can be peptone, glucose, sodium acetate, beef extract, amylum, etc. The change of molecular structure of the dye before and after decolorized by XL 1 is studied by UV Vis absorption spectrum. The results indicate that its molecular structure is changed evidently. | 董晓丽 Zhou Jiti Wang Jing Lu Hong | 2002 | High Technology Letters2002，8，2： | 6 |
| 4 | Removal of nitric oxide from simulated flue gas via denitrification in a hollow-fiber membrane bioreactor显示文摘A hollow-fiber membrane bioreactor(HMBR) was studied for its ability to treat nitric oxide(NO) from simulated flue gas. The HMBR was operated for 9 months and showed a maximum elimination capacity of 702 mg NO/(m2·day) with a removal efciency of 86%(gas residence time of 30 sec, inlet NO concentration of 2680 mg/m3, pH 8). Varying operation parameters were tested to determine the stability and response of the HMBR. Both the inlet NO concentration and gas residence time influenced the removal of NO in the HMBR. NO elimination capacity increased with an increase in inlet NO concentration or a shortening of gas residence time. Higher removal efciency of NO was obtained at a longer gas residence time or a lower inlet NO concentration. Microbial communities of the HMBR were sensitive to the variation in pH value and alkalescence corresponding to an optimum pH value of 8. In addition, NO elimination capacity and removal efciency were inversely proportional to the inlet oxygen concentration. Sulfur dioxide had no great influence on elimination capacity and removal efciency of NO. Product analysis was performed to study N2O and N2 production and confirmed that the majority of the microorganisms were denitrifying bacteria in the HMBR. Compared to other bioreactors treating NO, this study showed that the denitrifying HMBR was a good option for the removal of NO. | Xinyu Zhang Ruofei Jin Guangfei Liu Xiyang Dong Jiti Zhou Aijie Wang | 2013 | Journal of Environmental Sciences2013，25，11： | 5 |
| 5 | Biodegradation of indole by a newly isolated Cupriavidus sp. SHE显示文摘Indole, a typical nitrogen heterocyclic aromatic pollutant, is extensively spread in industrial wastewater. Microbial degradation has been proven to be a feasible approach to remove indole, whereas the microbial resources are fairly limited. A bacterial strain designated as SHE was isolated and found to be an efficient indole degrader. It was identified as Cupriavidus sp. according to 16 SrRNA gene analysis. Strain SHE could utilize indole as the sole carbon source and almost completely degrade 100 mg/L of indole within 24 hr. It still harbored relatively high indole degradation capacity within p H 4–9 and temperature 25°C–35°C. Experiments also showed that some heavy metals such as Mn2+, Pb2+and Co2+did not pose severe inhibition on indole degradation. Based on high performance liquid chromatography–mass spectrum analysis, isatin was identified as a minor intermediate during the process of indole biodegradation. A major yellow product with m/z 265.0605(C15H8N2O3) was generated and accumulated, suggesting a novel indole conversion pathway existed. Genome analysis of strain SHE indicated that there existed a rich set of oxidoreductases, which might be the key reason for the efficient degradation of indole. The robust degradation ability of strain SHE makes it a promising candidate for the treatment of indole containing wastewater. | Yuanyuan Qu E.Shen Qiao Ma Zhaojing Zhang Ziyan Liu Wenli Shen Jingwei Wang Duanxing Li Huijie Li Jiti Zhou | 2015 | Journal of Environmental Sciences2015，27，8： | 5 |
| 6 | An innovative membrane bioreactor and packed-bed biofilm reactor combined system for shortcut nitrification-denitrification显示文摘An innovative shortcut biological nitrogen removal system, consisting of an aerobic submerged membrane bioreactor (MBR) and an anaerobic packed-bed biofilm reactor (PBBR), was evaluated for treating high strength ammonium-bearing wastewater. The system was seeded with enriched ammonia-oxidizing bacteria (AOB) and operated without sludge purge with a decreased hydraulic retention time (HRT) through three phases. MBR was successful in both maintaining nitrite ratio over 0.95 and nitrification efficiency higher than 98% at HRT of 24 h, and PBBR showed satisfactory denitrification efficiency with very low effluent nitrite and nitrate concentration (both below 3 mg/L). By examining the nitrification activity of microorganism, it was found that the specific ammonium oxidization rate (SAOR) increased from 0.17 to 0.51 g N/(g VSS·d) and then decreased to 0.22 g N/(g VSS·d) at the last phase, which resulted from the accumulation of extracellular polymers substances (EPS) and inert matters enwrapping around the zoogloea. In contrast, the average specific nitrite oxidization rate (SNOR) is 0.002 g N/(g VSS·d), only 1% of SAOR. Because very little Nitrobactor has been detected by fluorescence in situ hybridization (FISH), it is confirmed that the stability of high nitrite accumulation in MBR is caused by a large amount of AOB. | ZHANG Yunxia, ZHOU Jiti, ZHANG Jinsong, YUAN Shouzhi School of Environmental and Biological Science and Technology, Dalian University of Technology, Dalian 116024, China. | 2009 | Journal of Environmental Sciences2009，21，5： | 5 |
| 7 | Quinone-mediated decolorization of sulfonated azo dyes by cells and cell extracts from Sphingomonas xenophaga显示文摘The effects of various quinone compounds on the decolorization rates of sulfonated azo dyes by Sphingomonas xenophaga QYY were investigated. The results showed that anthraquinone-2-sulfonate (AQS) was the most effective redox mediator and AQS reduction was the rate-limited step of AQS-mediated decolorization of sulfonated azo dyes. Based on AQS biological toxicity tests, it was assumed that AQS might enter the cells and kill them. In the cytoplasmic extracts from strain QYY, AQS more effectively increased decolorization rates of sulfonated azo dyes than other quinone compounds. In addition, we found a NADH/FMN-dependent AQS reductase using nondenaturing polyacrylamide gel electrophoresis (Native-PAGE). | JIAO Ling, LU Hong, ZHOU Jiti, WANG Jing School of Environmental and Biological Science and Technology, Key Laboratory of Industrial Ecology and Environmental Engineering (Ministry of Education), Dalian University of Technology, Dalian 116024, China. | 2009 | Journal of Environmental Sciences2009，21，4： | 4 |
| 8 | Coupled effects of methane monooxygenase and nitrogen source on growth and poly-β-hydroxybutyrate(PHB)production of Methylosinus trichosporium OB3b显示文摘The coupled effects of nitrogen source and methane monooxygenase(MMO) on the growth and poly-β-hydroxybutyrate(PHB) accumulation capacity of methanotrophs were explored.The ammonia-supplied methanotrophs expressing soluble MMO(s MMO) grew at the highest rate, while N_2-fixing bacteria expressing particulate MMO(p MMO) grew at the lowest rate. Further study showed that more hydroxylamine and nitrite was formed by ammonia-supplied bacteria containing p MMO, which might cause their slightly lower growth rate. The highest PHB content(51.0%) was obtained under nitrogen-limiting conditions with the inoculation of nitrate-supplied bacteria containing p MMO. Ammoniasupplied bacteria also accumulated a higher content of PHB(45.2%) with the expression of p MMO, while N_2-fixing bacteria containing p MMO only showed low PHB production capacity(32.1%). The maximal PHB contents of bacteria expressing s MMO were low, with no significant change under different nitrogen source conditions. The low MMO activity,low cell growth rate and low PHB production capacity of methanotrophs continuously cultivated with N_2 with the expression of p MMO were greatly improved in the cyclic NO_3-N_2 cultivation regime, indicating that long-term deficiency of nitrogen sources was detrimental to the activity of methanotrophs expressing p MMO. | Tingting Zhang Jiti Zhou Xiaowei Wang Yu Zhang | 2017 | Journal of Environmental Sciences2017，29，2： | 4 |
| 9 | Electrochemical degradation of p-nitrophenol with different processes显示文摘The electrochemical degradation of p-nitrophenol(PNP) under different conditions was investigated.The electrochemical behavior of PNP and its reduction product p-aminophenol(PAP) on stainless steel cathode and Ti/Pt anode through cyclic voltammetry were observed.Electrochemical degradation process was performed in an undivided cell and 92% PNP was removed corresponding to a 22% total organic carbon removal.A divided cell was also used and it was found that PNP degradation was mainly attributed to cathodic reduction,while anodic oxidation was responsible for PNP removal due to the reaction with hydroxyl radicals and surface oxide generated on the anode.The sequential electrolytic processes,reduction-oxidation and oxidation-reduction,were compared in the divided cell.In the case of reduction-oxidation process,the total organic carbon removal reached 40%,but PNP removal was the same with the undivided cell.A black deposit was found in the effluent and identified by Fourier transform infrared spectroscopy as a polymer of PAP produced by the 1,4-addition reaction of quinoneimine.Intermediates left in the solution such as hydroquinone,p-benzoquinone and PAP were determined by high performance liquid chromatography.Whereas,the oxidation-reduction process proved unsatisfying. | Ping Jiang,Jiti Zhou,Aili Zhang,Yijiang Zhong Key Laboratory of Industrial Ecology Environmental Engineering(MOE),School of Environmental & Biological Science & Technology,Dalian University of Technology,Dalian116024,China. | 2010 | Journal of Environmental Sciences2010，22，4： | 3 |
| 10 | Start-up of the anammox process from the conventional activated sludge in a hybrid bioreactor显示文摘The anaerobic ammonium oxidation (anammox) process was successfully started up from conventional activated sludge using a hybrid bioreactor within 2 months.The average removal efficiencies of ammonia and nitrite were both over 80%,and the maximum total nitrogen removal rate of 1.85 kg N/(m 3 ·day) was obtained on day 362 with the initial sludge concentration of 0.7 g mixed liquor suspended solids (MLSS)/L.Scanning electron microscope (SEM) observation of the granular sludge in the hybrid reactor clearly showed a high degree of compactness and cell sphericity,and the cell size was quite uniform.Transmission electron microscope photos showed that cells were round or oval,the cellular diameter was 0.6-1.0 μm,and the percentage of the anammoxosome compartment was 51%-85% of the whole cell volume.Fluorescence in situ hybridization analysis (FISH) indicated that anammox bacteria became the dominant population in the community (accounting for more than 51% of total bacteria on day 250).Seven planctomycete 16S rRNA gene sequences were present in the 16S rRNA gene clone library generated from the biomass and affiliated to Candidatus Kuenenia stuttgartiensis and Candidatus Brocadia sp.,a new anammox species.In addition,the average effluent suspended solid (MLSS) concentrations of outlets I (above the non-woven carrier) and II (below the non-woven carrier) were 0.0009 and 0.0035 g/L,respectively.This showed that the non-woven carrier could catch the biomass effectively,which increased biomass and improved the nitrogen removal rate in the reactor. | Xiumei Duan Jiti Zhou Sen Qiao Xin Yin Tian Tian Fangdi Xu | 2012 | Journal of Environmental Sciences2012，24，6： | 3 |
| 11 | Changes of microbial community structures and functional genes during biodegradation of phenolic compounds under high salt condition显示文摘The changes of microbial community structures and functional genes during the biodegradation of single phenol and phenol plus p-cresol under high salt condition were explored.It was found that the phenol-fed system(PFS) exhibited stronger degrading abilities and more stable biomass than that of the phenol plus p-cresol-fed system(PCFS).The microbial community structures were revealed by a modern DNA fingerprint technique,ribosomal intergenic spacer analysis(RISA).The results indicated that the microbial community of PFS changed obviously when gradually increased phenol concentration,while PCFS showed a little change.16S rRNA sequence analysis of the major bands showed that Alcanivorax sp.genus was predominant species during phenolic compounds degradation.Furthermore,amplified functional DNA restriction analysis(AFDRA) on phenol hydroxylase genes showed that the fingerprints were substantially different in the two systems,and the fingerprints were not the same during the different operational periods. | WANG Ping,QU Yuanyuan,ZHOU Jiti School of Environmental and Biological Science and Technology,Dalian University of Technology,Dalian 116024,China. | 2009 | Journal of Environmental Sciences2009，21，6： | 2 |
| 12 | Enrichments of methanotrophic–heterotrophic cultures with high poly-β-hydroxybutyrate(PHB) accumulation capacities显示文摘Methanotrophic–heterotrophic communities were selectively enriched from sewage sludge to obtain a mixed culture with high levels of poly-β-hydroxybutyrate(PHB)accumulation capacity from methane.Methane was used as the carbon source,N_2as sole nitrogen source,and oxygen and Cu content were varied.Copper proved essential for PHB synthesis.All cultures enriched with Cu could accumulate high content of PHB(43.2%–45.9%),while only small amounts of PHB were accumulated by cultures enriched without Cu(11.9%–17.5%).Batch assays revealed that communities grown with Cu and a higher O_2content synthesized more PHB,which had a wider optimal CH_4:O_2range and produced a high PHB content(48.7%)even though in the presence of N_2.In all methanotrophic–heterotrophic communities,both methanotrophic and heterotrophic populations showed the ability to accumulate PHB.Although methane was added as the sole carbon source,heterotrophs dominated with abundances between 77.2%and 85.6%.All methanotrophs detected belonged to type II genera,which formed stable communities with heterotrophs of different PHB production capacities. | Tingting Zhang Xiaowei Wang Jiti Zhou Yu Zhang | 2018 | Journal of Environmental Sciences2018，30，3： | 2 |
| 13 | Biosynthesis of gold nanoparticles by Trichoderma sp.WL-Go for azo dyes decolorization显示文摘Developing an eco-friendly approach for metallic nanoparticles synthesis is important in current nanotechnology research. In this study, green synthesis of gold nanoparticles(AuNPs) was carried out by a newly isolated strain Trichoderma sp. WL-Go. UV–vis spectra of Au NPs showed a surface plasmon resonance peak at 550 nm, and transmission electron microscopy images revealed that the Au NPs were of varied shape with well dispersibility.The optimal conditions for Au NPs synthesis were HAuCl_4 1.0 mmol/L, biomass 0.5 g and pH 7–11. Moreover, the bio-Au NPs could efficiently catalyze the decolorization of various azo dyes. This research provided a new microbial resource candidate for green synthesis of Au NPs and demonstrated the potential application of bio-Au NPs for azo dye decolorization. | Yuanyuan Qu Wenli Shen Xiaofang Pei Fang Ma Shengnan You Shuzhen Li Jingwei Wang Jiti Zhou | 2017 | Journal of Environmental Sciences2017，29，6： | 2 |
