微生物降解呋喃丹的研究进展

摘要

呋喃丹(2,3-二氢-2,2-二甲基-7-苯并呋喃基甲氨基甲酸酯)是一种曾被广泛应用于农业生产的氨基甲酸酯类杀虫剂.虽然呋喃丹现在是我国的限制使用农药品种,但是它的残留仍然破坏生态环境和威胁人体健康.微生物降解是消除环境中呋喃丹污染的有效手段,但是目前对微生物降解呋喃丹的分子机制还未阐明.本文从微生物菌株资源、降解途径、关键酶和基因等几个方面综合阐述了国内外对微生物降解呋喃丹的最新研究进展,为呋喃丹污染环境的生物修复提供参考.%Carbofuran,2,3-Dihydro-2,2-dimethyl-7-benzofuranol N-methylcarbamate,is a carbamate pesticide which has been used widely in agricultural production.Although the use of carbofuran is restricted now in China,its residues are still destroying the ecological environment and threatening the human health.Microbial degradation is an effective measure to eliminate the environment pollution of carbofuran,but the molecular mechanism of microbial degradation of carbofuran has not been clarified.The latest research progress on the degradation of carbofuran at home and abroad are reviewed from the aspects of microorganism resource,degradation pathway,key enzymes and genes,to provide reference for bioremediation of carbofuran-contaminated environments.
