摘要：

Growth of a PCB degrader Rhodococcus sp. RHA1 on biphenyl and ethylbenzene was inhibited by 100 mu g/ml PCB 48. A PCB tolerant derivative of RHA1 designated RCD1 was deficient in growth on biphenyl. Southern hybridization experiments suggested that RCD1 has the bphDE gene deletion in a 390-kb linear plasmid of RHA1. The bphD gene complementation restored growth deficiency on biphenyl and growth inhibition on ethylbenzene by PCB 48, indicating that PCB metabolites are the cause of growth inhibition.
