Pesticides play an important role in agriculture in developing countries, especially in India. Their significance in improving crop yield is well known and understood. The Continuous use of pesticides in fields is harmful as some pesticides remain in the soil for longer periods of time and enter the food chain that affects animals and humans. The current study is aimed at developing the method of biodegradation to reduce the pesticide's environmental burden. In the present study, Malathion degrading bacterial isolates have been isolated from various cultivated soil samples. The different isolates were characterized by various biochemical tests for identification. Among the 22 isolates, a potential isolate of Bacillus pumilus was utilized for the optimization process. The degradation level was determinate with an optical density of biomass. Furthermore, the potential isolate was subjected to the production of Organophosphorous phosphatise, after dialysis, 51.04U/ml of the enzyme was observed. Thus, this isolated bacterial species could be used as potential candidates for bacterial mediated bioremediation of pesticide.
