Abstract:

This investigation aims to explore mechanisms of microbiological detoxification of residual organophosphorus pesticide - chlorpyriphos using certain soil heterotrophs like Pseudomonas aeruginosa NCIM 2036, Bacillus subtilis NCIM 2010, Bacillus cereus NCIM 2156, Micrococcus luteus NCIM 2103 and Galactomyces geotrichum MTCC 1360 by comparing with dimethoate and monocrotophos. Organophosphorus class of pesticides has evolved after the gross misuse of organochlorine pesticides like DDT having a half life of 5 years in agricultural soils. Therefore, the pharmacodynamics of the residues often led to effects like mutagenesis, carcinogenesis and teratogenesis in higher animals including humans. It was observed that common heterotrophs like Bacillus subtilis NCIM 2010, Bacillus cereus NCIM 2156, Micrococcus luteus NCIM 2103 brought about degradation of Monocrotophos, Chlorpyriphos and Dimethoate along with Galactomyces geotrichum MTCC 1360. However, though Pseudomonas aeruginosa NCIM 2036 was found to degrade Monocrotophos, dimethoate but could not detoxify chlorpyriphos.
