Bacterial degradation of PCB in Sydney Harbour sediment / F.I. Onuska [and three others]. : En13-5/99-78E-PDF
"The degradation of PCBs by two biphenyl-utilizing bacterial strains, Alkaligenes xylosoxidans and Pseudomonas stutzeri, was studied in sediment from Sydney Harbour, Nova Scotia which was contaminated by PCBs and coal tar. In addition to the congener specificity, significant differences were observed between the two bacterial strains in the degradation of PCBs in different sediment samples. The efficiency of degradation was generally low for higher chlorinated congeners. These results indicate that the degradation of PCBS is probably related not only to the bacterial strain employed and the high concentration of PAHs in the sediment, but also to sediment sorption of the PCB congeners. The degradation is faster in sediments containing an intermediate amount of organic carbon with a high proportion of total aromatic carbon in the humic acid fraction. This study was supported by the North Atlantic Treaty Organization"--Abstract.
