Abstract:

Current study is based on biodegradation of organophosphorus pesticide dimethoate in liquid MSM medium with P. sutzeri. It was found to be capable of utilizing dimethoate as sole carbon and energy source and could rapidly utilized dimethoate beyond 100 ppm and showed maximum growth in MSM. The concentration of the dimethoate in the solution decreased exponentially with the increased exposure time. P. sutzeri could tolerate dimethoate from 100 ppm to 900ppm. In current study, several factors influencing dimethoate degradation were investigated. Complete disappearance of dimethoate was detected within 72 h of incubation. UV-Visible spectroscopic analysis (660 nm) revealed the complete mineralization of dimethoate. The optimal pH and temperature growth conditions were 8.5 and 30°C, respectively. The microbial consortia could prove to play a valuable role for the bioremediation of dimethoate contaminated field soil.
