Abstract

The bacterial strain P2 degrading polychlorinated biphenyls (PCBs) was isolated from the soil around the Shinchun stream in Taegu after enrichment culture in a media containing biphenyl as the sole carbon source. The isolate was identified as a strain of Pseudomonas sp. based on its morphological and physiological characteristics. The optimal conditions of initial pH of media and temperature for growth were 7.0 and $30^{\circ}C$, respectively. Degradation of biphenyl and PCBs was confirmed by GC during the culture of Pseudomonas sp. P2 in a media containing them at a concentration of 500 mg/I. It was observed that Pseudomonas sp. P2 could degrade 97.0$%$ of biphenyl and 60.0$%$ of PCBs after 160 h culture.
