Biphenyl dioxygenase (BPDO) catalyzes the aerobic transformation of biphenyl and various polychlorinated biphenyls (PCBs). In three different assays, BPDO(B356) from Pandoraea pnomenusa B-356 was a more potent PCB-degrading enzyme than BPDO(LB400) from Burkholderia xenovorans LB400 (75% amino acid sequence identity)

The capability of Rhizobium meliloti on degrading 2,4,4'-trichlorobiphenyl and 18 kinds of polychlorinated biphenyl congener mixtures was studied by shaking flask experiment. The results showed that the degradation capability of Rhizobium meliloti to 2, 4, 4'-trichlorobiphenyl increased gradually with the
