As one of the transition metals, vanadium（V）（V（V）） in trace amounts represents an essential element for normal cell growth, but becomes toxic when its concentration is above 1 mg/L. V（V） can alter cellular differentiation, gene expression, and other biochemical and metabolic phenomena. A feasible method to detoxify V（V） is to reduce it to V（IV）, which precipitates and can be readily removed from the water. The bioreduction of V（V） in a contaminated groundwater was investigated using autohydrogentrophic bacteria and hydrogen gas as the electron donor. Compared with the previous organic donors,H2 shows the advantages as an ideal electron donor, including nontoxicity and less production of excess biomass. V（V） was 95.5% removed by biochemical reduction when autohydrogentrophic bacteria and hydrogen were both present, and the reduced V（IV）precipitated, leading to total-V removal. Reduction kinetics could be described by a first-order model and were sensitive to p H and temperature, with the optimum ranges of p H 7.5–8.0 and 35–40°C, respectively. Phylogenetic analysis by clone library showed that the dominant species in the experiments with V（V） bioreduction belonged to theβ-Proteobacteria. Previously known V（V）-reducing species were absent, suggesting that V（V）reduction was carried out by novel species. Their selective enrichment during V（V）bioreduction suggests that Rhodocyclus, a denitrifying bacterium, and Clostridium, a fermenter known to carry out metal reduction, were responsible for V（V） bioreduction.

River waters in China have dual contamination by nutrients and recalcitrant organic compounds. In principle, the organic compotmds could be used to drive denitrification of nitrate, thus arresting eutrophication potential, if the recalcitrant organics could be made bioavailable. This study investigated the potential to make the recalcitrant organics bioavailable through photocatalysis. Batch denitrification tests in a biofilm reactor demonstrated that dual-contaminated river water was short of available electron donor, which resulted in low total nitrogen （TN） removal by denitrification. However, the denitrification rate was increased signifi- cantly by adding glucose or by making the organic matters of the river water more bioavailable through photocata- lysis. Photocatalysis for 15 min increased the Chemical Oxygen Demand （COD） of the river water from 53 to 84 mg. L-1 and led to a 4-fold increase in TN removal. The increase in TN removal gave the same effect as adding 92 mg.L 1 of glucose. During the photocatalysis experi- ments, the COD increased because photocatalysis trans- formed organic molecules from those that are resistant to dichromate oxidation in the COD test to those that can be oxidized by dichromate. This phenomenon was verified by testing photocatalysis of pyridine added to the river water. These findings point to the potential for N removal via denitrification after photocatalysis, and they also suggest that the rivers in China may be far more polluted than indicated by COD assays.

环境生物技术是一门利用微生物介质为人类提供服务的技术科学,其核心思想是依据各类微生物的生态活动规律,从中寻找最有效的能解决目前一些环境问题的途径,如稀释污染物、截留废物中的可循环利用资源等．在过去15年里,分子生物技术的广泛使用,为逐步掌握微生物生态活动规律提供了可能,如:它们是如何自组织繁衍的,不同类体之间是如何相互影响的;同时,一些新的数学模型方法和新材料的尝试使用,也极大地拓宽了学科研究的手段．目前,有两种力量正在推动该学科的进行,一是其他学科领域的发展所带来的“推力”,二是社会的环境安全需求所产生的“拉力”．为了利用这种大好的发展时机,未来学科的研究要注意以下4个方面:①把解决水和能源可持续发展问题放在首要位置;②开发和采用更有效的分子技术工具去揭示微生物的生态活动规律;③综合利用分子技术工具、模型分析工具和采用新材料去努力解决实际环境问题;④要注重生物膜技术的研究．还提供了几个案例说明了如何把这4个方面的思想贯彻到实际研究之中．

环境生物技术所从事的是"使微生物群落能为人类社会提供服务",它的成功来自与原核微生物的协同作用,其广泛的代谢能力可以被利用来破坏污染物的结构并产生可再生材料.要想发挥微生物的作用,需要通过微生物分子生态学、分析化学和数学建模等学科的发展去很好地理解它,从而看清微生物黑箱模型内部的本质.同样重要的是将对生物技术的理解转化为"利用好微生物以使他们为我们工作".这种转化需要新颖的反应器设计,先进材料的利用,以及与用户的良好合作.成立于2005年的亚利桑那州立大学Swette环境生物技术中心,就是将相关的科学与工程领域中的多种方法和手段汇集在一起,形成了一种跨学科的研究中心.该中心强调团队协作精神,并与世界各地的研究者和实践者进行合作.介绍了3个新的技术:用于消减水中许多氧化性污染物的H2基膜生物膜反应器(MBfR);用于有机污染物转化为可再能源的微生物电化学电池(MXCs);以及用于加速难生物降解有机污染物脱毒的光催化与生物降解紧密结合的光-生物催化技术说明了中心是如何将基本原理应用于"利用好微生物"的.
