摘要
有机磷农药是目前我国使用量最大的农药 ,对农业的发展有重要的作用 ,但同时造成了严重的环境污染 .利用微生物或微生物源酶制剂来降解农药是近年来的一个主要努力方向 .至今 ,已经陆续分离到许多有机磷降解菌 ,并对其相应的降解酶的生化性质进行了鉴定 ,相关的基因也被克隆、鉴定和改造 .另外 ,基因工程及生物技术方面的进展为开发微生物或酶制品奠定了基础 .本文综述了有机磷农药降解菌、降解酶以及有机磷农药生物降解技术等方面的研究现状 .表 1参 6
Organophosphate compounds (OPs) are most extensively used pesticides around the world. Although OPs have playing important roles in protecting agricultural crops from insect pests and weeds, and in controlling disease-transmitting vectors, they cause serious environmental pollution problems. The biotechnology involving the use of microorganisms or their cell-free enzyme preparations in degrading pesticides appears to have, at the moment, the most promising applications in degrading the residual pesticides. Microorganisms capable of degrading many of organophosphorus pesticides have been isolated, many enzymes have also been characterized, and various OPs degrading genes have been cloned and identified. These findings offer great possibilities to exploit these degrading microorganisms and enzymes. In this article, the current knowledge of the organophosphate biodegradation was summarized.
