Abstract


The present investigation dealt with the isolation of Methyl Parathion degrading microorganisms from rhizospheric soil of selected plants. The isolates were biochemically identified as Pseudomonas aeruginosa,
Bacillus megaterium and Staphylococcus aureus. These microorganisms could degrade Methyl Parathion upto 350 μg/ml concentration. Among all isolates the highest incidence was of Bacillus megaterium followed by Pseudomonas aeruginosa and Staphylococcus aureus.

Keywords
