Since 1960s, the organophosphate pesticide chlorpyrifos has been widely used for the purpose of pest control. However, given its persistence and toxicity towards life forms, the elimination of chlorpyrifos from contaminated sites has become an urgent issue. For this process bioremediation is the method of choice.
Two bacterial strains, JCp4 and FCp1, exhibiting chlorpyrifos-degradation potential are isolated from pesticide contaminated agricultural fields.These isolates were able to degrade 84.4% and 78.6% of the initial concentration of chlorpyrifos (100 mg L-1) within a period of only 10 days.
The results clearly demonstrate that the chlorpyrifos-degrading strains have the potential to develop into promising candidates for raising the productivity of crops in pesticide contaminated soils.

go to agricultural field, where pesticides and herbicides are mostly.
collect soil sample from there and culture and isolate different strain the on solid medium, then test it by adding pesticides into culture. if bacteria present in that then they might be shown extra growth or other phenomenon.
