【摘要】 以活性污泥法为代表的生物处理技术一直是人类解决废水问题的主要手段,而微生物在环境污染物分解中更是发挥了无法替代的作用。长期以来,阐明环境净化中的微生物生态学过程,探讨污染物降解转化中微生物的作用机制,是环境科学与工程领域关注的热点问题之一。近年来迅速发展起来的分子生物学技术为人们认识人工系统以及自然环境中微生物的群落结构、功能和微生物之间的相互作用,以及构筑更加高效的生物处理系统、强化污染环境的修复能力提供了有力手段。本文在介绍了常用分子生物学方法的基础上,阐述了在废水处理及污染物降解方面微生物生态学的研究进展。更多还原

【Abstract】 Biological treatment technologies,especially activated sludge methods,have long been the main solution for wastewater treatment,and microbes have played a key role in the degradation of environmental pollutants.Elucidating microbial ecological processes and microbial functions during pollutants degradation in both artificial and natural biological systems have been the hot issues in environmental science and engineering field.The fast developing molecular biology techniques provide not only the powerful tools for probing microbial community structures,functions and microbial interactions in different systems,but also scientific bases for constructing efficient biological systems for the removal of environmental pollutants.This review summarizes the most often used molecular methods and the recent research results in environmental microbial ecology studies.更多还原
