Abstract: Chemical pesticides mainly organophosphorus pesticides are widely used for crop protection and to increase productivity. The excessive use has led to its bioaccumulation in the environment leading to generation of various health hazards. One such organophosphorus pesticide is Methyl Parathion. The objective of this study is the biodegradation of this hazardous methyl parathion through nitrogen fixing bacteria. In this investigation the degradation of methyl parathion was studied by thin layer chromatography. The potential degraders were Azotobacter spp., Bradyrhizobium spp., Mezorhizobium spp., Rhizobacterium spp. and Azospirillium spp., etc. Bioremediation plays a key role in order to combat from this bioaccumulation using microorganism involving the preliminary step that is study of biodegradation of methyl parathion through nitrogen fixing bacteria. This study revealed that Azotobacter spp. and Rhizobium spp. could biodegrade harmful methyl parathion. Further studies could be carried out by using molecular techniques to formulate the suitable innoculum for the development of effective bioremediation strategy to decontaminate harmful methyl parathion.
