摘要: 多氯联苯是一种持续性有机污染物,在自然环境中很难降解。在目前研究的降解方法中,微生物降解最具潜力。本文对多氯联苯微生物降解的研究进展进行了综述,包括厌氧还原脱氯,好氧氧化以及生物表面活性剂的作用,介绍了几种降解方法耦合应用的现状和前景,指出了应用中存在的问题和今后的发展方向。

Abstract: As one of the persistent organic pollutants, polychlorinated biphenyls (PCBs) are rarely degraded in the environment, while biodegradation is an effective way to remove PCBs from contaminated soil and sediments.This paper reviewed the effects of aerobic oxidation,anaerobic dechlorination, and biosurfactants in the microbial degradation of PCBs, introduced the application and potentials of coupling several removal methods, and pointed out the applied issues and the directions of further studies.
