摘要
指出了有机磷农药在我国的使用量很大,不但污染环境,还经过食物链将有毒物质富集在生物体内,进一步危害人类。微生物降解技术是一种降解效率高、代谢方式多、耗费成本底、反应条件比较温和、无二次污染的技术,是降解有机磷农药的重要方法,这种技术能够很大程度的降低有机磷农药对环境和人类产生的危害。综述了有机磷降解菌的降解措施、菌的筛选分离、分类鉴定和种类以及降解机理的进展,为有机磷农药的微生物降解技术的使用研究提供参考。
At present,organophosphorus pesticides are widely used in China.It not only pollutes the environment,but also enriches toxic substances in living organisms through the food chain,further harming humans.Microbial degradation technology is a technology with high degradation efficiency,multiple metabolic methods,cost-consuming bottom,mild reaction conditions and no secondary pollution.It is an important method for degrading organophosphorus pesticides.This technology can greatly reduce the environmental and human harm caused by organophosphorus pesticides.In this paper,the degradation measures of organophosphate degrading bacteria,the screening and isolation of bacteria,the classification and identification,and the progress of degradation mechanism are reviewed,which provides a reference for the use of microbial degradation technology of organophosphorus pesticides.
