Dechlorination of polychlorinated biphenyls (PCBs) by nanoscale zerovalent iron (NZVI) is often strongly hindered by increased pH because large amounts of H(+) ions were consumed during the surface reaction. The main objective of this work was to evaluate the effect

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)
