Abstract

Several bacterial isolates were characterized based on their abilities to degrade specific polychlorinated biphenyls (PCBs) and their 16S rRNA gene sequences. The members of one group of bacteria consisting of Alcaligenes species, including the PCB-degrading bacterium Alcaligenes eutrophus H850, had strong abilities to degrade a broad range of PCBs but not the di-para-chlorine-substituted congeners. The members of another group, which included the PCB-degrading bacterium originally classified as Corynebacterium sp. strain MB1, had strong abilities to degrade di-para-chlorine-substituted PCBs. These bacteria were most likely different members of Rhodococcus species.
