有机氯农药的微生物降解

Microbial Degradation of Organochlorine Pesticides

有机氯农药是广泛应用于农业生产的高效杀虫剂。虽在20世纪60年代被禁用,但其在环境中的残留对生态环境和人类健康仍然造成很大的威胁。目前降低环境中有机氯农药污染的有效手段是采用微生物降解的方法。介绍了近年来我国有机氯农药的污染现状,重点总结了国内外5种主要有机氯农药的微生物降解方面的研究进展及其降解酶和降解基因,并展望了有机氯农药微生物降解的发展前景,为有机氯农药污染环境的生物修复提供了参考。

Organochlorine pesticides are highly effective insecticides widely used in agricultural production.Although they are banned in the 1960s,their residues in the environment still pose a great threat to the ecological environment and human health.At present,microbial degradation is an effective means to reduce the pollution of organochlorine pesticides in the environment.In this paper,we introduce the pollution status of organochlorine pesticides in recent years in China,summarize the research process of microbial degradation of five main organochlorine pesticides and degradation enzyme and genes at home and abroad,and put forward the development prospect of microbial degradation of organochlorine pesticides,so as to provide a reference for the bioremediation of organochlorine-pesticide-polluted environment.
