ABSTRACT
Endosulfan degrading bacteria were isolated from insecticide contaminated soils from coffee plantations of Coorg District, Karnataka state. Three strains of endosulfan degrading bacteria were isolated and characterized as Bacillus, Pseudomonas and Nocardia sp. Bacterial colonies were tested for endosulfan utilization. Bacillus and Nocardia sp grew well in the mineral medium containing endosulfan as the only carbon source. The degradation of endosulfan was followed by monitoring growth of culture, residual endosulfan and the metabolites formed in the medium. Analysis of culture medium showed disappearance of the parent molecule with formation of very negligible amount of endosulfan sulfate. The bacterial strain isolated in the present study seems to be a strong candidate for bioremediation of plantation soils contaminated with endosulfan.
Key words :
Bacillus, Endosulfan diol, Degradation, Nocardia, Tolerant strains.
