A gram-positive strong polychlorinated biphenyl (PCB) degrader, Rhodococcus sp. strain RHA1, can degrade PCBs by cometabolism with biphenyl or ethylbenzene. In RHA1, three sets of aromatic-ring-hydroxylating dioxygenase genes are induced by biphenyl. The large and small subunits of their terminal dioxygenase components are encoded by bphA1 and bphA2, etbA1 and etbA2, and ebdA1 and ebdA2, respectively, and the deduced amino acid sequences of etbA1 and etbA2 are identical to those of ebdA1 and… CONTINUE READING
