Biodegradation is one of the efficient processes for detoxification of many pesticides and their metabolites from the environment. The present study evaluates the biodegradation of endosulfan by Pseudomonas (IES-Ps-I) through growth kinetic studies for 29 h and its further monitoring through gas chromatography technique. After initial inoculation the acclimatization phase of IES-Ps-1 continued up to 3 h and significantly increased the optical density (O.D550) of broth after 4 h of incubation. This increase in O.D550 continued after 24 h, indicating that the culture was in log phase. IES-Ps-1 showed 50% reduction in peak amount of pesticide when grown in broth supplemented with 10mg/L and 25mg/L. Endosulfan disappearance was concomitant when this adapted culture was grown at high concentration of pesticide, i.e. 50mg/L and 100mg/L and gave more than 80% reduction at 29 h.
