Abstract:

Two bacterial isolates (Pseudomonas sp. GSa and Pseudomonas sp. GSb) were in close association able to assimilate 2,4 dichlorobiphenyl (2,4 CB), a PCB congener. GC-MS analysis of spent culture medium of the consortium with 2,4 CB as substrate showed 90 % degradation (according to Electron capture detection values) with catechol as one of the important intermediate compounds through meta-cleavage pathway. Further, ability of the consortium to utilise PCB congeners, Methoxychlor, Aroclor 1016, Chlorobenzoic acids and Monoaromatic compounds indicated that the consortium of GSa and GSb would be an ideal candidate for in situ bioremediation of PCB.
