摘　　要：近年来,由于高毒有机氯和有机磷农药被禁止使用,拟除虫菊酯类农药(pyrethroids,PYRs)因其高效性和稳定性被广泛应用于农业生产及环境中,但其频繁使用所带来的残留危害也日渐突出。3-苯氧基苯甲酸(3-phenoxybenzoic acid,3-PBA)是PYRs的主要代谢产物之一,为环境雌激素类物质,具有较大的潜在危害性。农药残留严重影响了人们的生产和生活,同时引起了研究人员的广泛关注,PYRs和3-PBA降解菌被大量报道,微生物及其降解酶对农产品和环境中农药残留的去除或减除也是公认的有效方法之一,并且基因工程和分子生物学技术的不断发展为继续深入发掘减除农药残留的方法提供了新途径。本文概述PYRs和3-PBA的基本性质、残留危害,综述PYRs对农产品和环境的残留现状、微生物对PYRs的代谢方式与吸附和降解机制研究进展,并对其降解酶及酶基因工程进行展望,旨为解决农产品和环境中农药残留问题提供参考。The use of organochlorine and organophosphorus pesticides has been prohibited due to their highly toxicity.In recent years,pyrethroids(PYRs)have been widely used in agricultural production and the environment due to their high efficiency and stability,but the residual hazards caused by their frequent use have become increasingly prominent.3-Phenoxybenzoic acid(3-PBA)is one of the major metabolites of PYRs,which is an environmental estrogen with great potential harms.Pesticide residues have seriously affected people’s production and life,which has attracted extensive attention from researchers.PYRs and 3-PBA degrading bacteria have been widely reported,and microbial and enzymatic degradation is recognized as an effective method for reducing or removing pesticide residues from agricultural products and the environment.The continuous development of genetic engineering and molecular biology technology provides a new way to explore methods for reducing pesticide residues.In this article,we summarize the basic properties and residual hazards of PYRs and 3-PBA,and we review the current status of PYRs residues in agricultural products and the environment as well as recent progress in research on the modes of microbial metabolism and the mechanisms of microbial adsorption and degradation of PYRs.Moreover,we give an outlook on enzymes degrading PYRs and their genetic engineering in order to provide a reference for solving the problem of pesticide residues in agricultural products and the environment.
