| characterization of multiple novel aerobic polychlorinated biphenyl (pcb)-utilizing bacterial strains indigenous to contaminated tropical african soils. | contaminated sites in lagos, nigeria were screened for the presence of chlorobiphenyl-degrading bacteria. the technique of continual enrichment on askarel fluid yielded bacterial isolates able to utilize dichlorobiphenyls (dicbs) as growth substrates and six were selected for further studies. phenotypic typing and 16s rdna analysis classified these organisms as species of enterobacter, ralstonia and pseudomonas. all the strains readily utilized a broad spectrum of xenobiotics as sole sources of ... | 2008 | 17534725 |
