White rot fungi play significant role in biological dissipation of Organochlorine (DDT, HCH, Aldrin, Dieldrin, Endrin, Endosulfan and Heptachlor) in ecosystem. Relative biodegradation potential of Pleurotus ostreatus(OST-1), Pleurotus pulmonarious (Sajor- Caju)(WC-537),Pleurotus ostreatus( WC-522), A-6 and R-22 (Pleurotus ostreatus) against above pesticides were studied by using GC-ECD. HCH was degraded 84% by OST-1 which is a local strain, followed by A-6 (55%), WC-522 (45%), OST-Belgium (29%) and WC-537 (4%) which are exotic strains of Pleurotus. Maximum Degradation of 4,4-DDT and 2,4-DDT was done by OST-1(67% and 65%)respectively. Influence of A-6 (69%), OST-Belgium (69%) and WC-537 (51%) was more pronounced for 4,4-DDT than for 2,4-DDT with only 14%, 16% and 0% respectively. Exotic strain of P. ostreatus (WC-522) was the most inefficient of the isolates and produced only 3% reduction in 2,4-DDT and no reduction was observed in case of 4,4-DDT. In the study only A-6 and OST-1 were found to produce some reduction while OST-Belgium, WC-522 and WC-537 did not produce any amount of reduction in aldrin and dieldrin quantities. Efficacy of isolates varied significantly with each other for a-endosulfan and b-endosulfan A-6 and OST-1 were found most efficient and at par with each other in reducing the amount of α-and β-endsulfan in bioassay. Mean maximum reduction of Endrin 32% was recorded in WC-537 followed by 29% in WC-522 and 14% in OST-Belgium. Isolates also vary greatly in degradation of heptachlor. Based on results it is highly recommended to use local Pleurotus isolates of Particular area where bioremediation need to be done.
