有机磷农药的微生物降解技术研究进展

目前有机磷农药是应用广泛、品种最多的农药,传统的物理和化学方法降解有机磷农药虽然效果好,但成本高且易造成二次污染,而随着生物技术的不断发展,微生物在农药降解方面的应用前景十分广阔。文章介绍了有机磷农药的生产和应用现状、降解有机磷农药的微生物种类、影响微生物降解有机磷农药的因子、微生物降解有机磷农药的途径等,指出降低或消除环境因素对微生物降解有机磷农药的不利影响,使微生物发挥最大的作用,是未来农药降解研究的热点。

Research progress on technologies for microbial degradation of organophosphorus pesticide

At present,organophosphorus pesticides are being widely used in agriculture for sustaining productivity,however,their degradation in nature is a great problem causing threats to the natural environment.There are many conventional and physico-chemical methods for organophoshorus degradation which are though effective,but are uneconomic,and may cause secondary pollution to the environment.With the development of biotechnology,the prospective of microorganism degradation of organophoshorus has been explored in order to reduce their deposition in the agricultural soils.This paper discusses about production and application status quo of organophosphorus pesticide,types of microorganism useful for decomposing the organophosphorous pesticide,influencing factors and approaches for developing a method for microbial degradation of organophosphorous pesticides.It also pointed out that reducing and eliminating the adverse effects of environmental factors for microorganism degradation microbial.
