Polychlorinated biphenyls (PCBs) are Persistent Organic Pollutants (POPs)。This experiment screened a halophilic bacterium from the deep sea sediments，which could grow at the salinity of 15%，and designated as B2。6。The cells of this strain were rod shaped，Gram negative，motile。Growth of this bacterium in the presence of PCBs，as the sole source of carbon and energy，and the experiment indicated that at 30℃ when pH value is between 7 and 8，inoculation amount is 5mL，the concentration of PCBs is below 3mg·L-1 and the ratio of degradation could reach 90% at 72h。The traditional morphology，physiological and biochemical properties as well as identified system of Biolog were applied to the bacterial classification。The pattern of PCBs-degrading enzyme production of strain B2。6 was continuous synthesis。
