Bacterial bioremediation of organophosphorus pesticides

Approximately 5.6 billion pounds of pesticides are consumed annually around the world. The important environmental impact in this regard is that the pesticides are continuously displaced from one environment to another, and leave negative effects in each environment. Studies have shown that more than 98% of insecticides and 95% of sprayed herbicides reach other targets (other than their main purpose), including non-target species, air, water, soil and food. Various physical, chemical and biological methods have been developed to reduce the environmental impacts of pesticides, in which microbiological remediation is one of the least harmful methods for the elimination of contaminants. Considering the effect of plant growth promoting rhizobacteria (PGPR) on improving plant growth, the use of these bacteria for bioremediation of pesticide can increase their competitive ability of bio-based product in the market. In this paper, it has been attempted in the first step to address some of the destructive aspects of organic phosphorus pesticides as one of the most important pesticides. Further, an effective solution to refining these types of insecticides is mentioned.
