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.
