| 英文摘要 | his study is aimed to investigate the degradation characteristics of PCBs-degrading strain screened and isolated from estuary utilizing biphenyl as sole carbon and energy source. Pseudomonas sp. P-6-5 was investigated in more details of growth and substrate utilization pattern towards BPH and PCB3. The optimal growth conditions for strain P-6-5 were pH 7.0 and salinity 35 g/L. The use of BPH and PCB3 as an inducing agent promoted the growth of degrading bacteria. Strain P-6-5 had the transformation ability to PCB3 with substrate concentration of 10-100 mg/L. The degradation rate of PCB3 by strain P-6-5 was 95.3% in cultures containing 10 mg/L PCB3 and the maximum degradation speed was 1.9 mg/L·h. The PCBs substrate spectrum was assessed by mix13(a mixture of 13 PCB congeners)and the data showed that P-6-5 had the ability to degrade up to four chlorinated polychlorinated biphenyls. Combined with product analysis,we speculated that strain P-6-5 may have the ability to mineralize PCB3. In conclusion,Pseudomonas sp. P-6-5 has the characteristics of seawater bacteria and shows a broad range of substrate spectrum. These results postulate that the P-6-5 is an efficient PCBs-degrading strain,and has a great potential to be utilized in the bioremediation of PCBs pollution. |
