微生物在污染环境生物修复中的应用

生物修复是一项利用生物特别是微生物治理污染的技术。与理化修复方法相比具有投资少、对环境影响小的优点。本文重点分析了影响微生物修复的关键因素,包括生物因素、营养因素、O2和电子受体、表面活性剂和共代谢物等,并介绍了微生物在生物修复中成功应用的实例,讨论了生物修复所具有的优势和存在的不足及今后研究重点。

Application of microorganism in bioremediation of contaminated environment

Bioremediation is a technique that uses living organisms,micro-organism in particular,to remove pollutants from contaminated environments.Bioremediation has gained momentum in recent years because of its low investment requirement and environmental impact as compared with other remediation techniques and has thus become a viable and promising mode for restoring contaminated sites.In this paper,key factors,including biological factors,nutrient factors,O2 and electronic receptors,surfactants,co-metabolites,that affect bioremediation are discussed,some successful examples of bioremediation are given,and the merits and demerits of bioremediation expounded.
