A bacterial co-culture, ECO3, constituted by a polychlorobiphenyl degrading bacterium, Pseudomonas sp. strain CPE1, and two chlorobenzoic acid degrading bacteria, could grow on Aroclor 1221 (75 mg/L) as the sole carbon source without accumulating chlorinated aromatic metabolites in the medium;
The hybrid Pseudomonas cepacia strain JHR22 was tested for its ability to degrade Aroclor 1221 in soil. The influence of supplements--mineral salts and trace elements--on the degradation was investigated. Disappearance of Aroclor 1221 congeners, occurrence of metabolites, and release of

Polychlorinated biphenyls (PCBs) are a family of toxicants that persist in measurable quantities in human and wildlife tissues, despite their ban in production in 1977. Some PCB mixtures can act as endocrine disrupting chemicals (EDCs) by mimicking or antagonizing the
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
