The comparative biologic and toxic potencies of polychlorinated biphenyls and polybrominated biphenyls

Toxicology and Applied Pharmacology, 1983
Aroclor 1254 and fireMaster BP-6, two commercial polychlorinated biphenyl (PCB) and polybrominated biphenyl (PBB) preparations, exhibit comparable biologic and toxic effects. In the present study the commercial PBB was more active than Aroclor 1254 in causing thymic atrophy in male Wistar rats.

Enhanced degradation of polychlorinated biphenyls by directed evolution of biphenyl dioxygenase

Nature Biotechnology, 1998
Biphenyl dioxygenases (BP Dox) from different organisms, which are involved in the initial oxygenation and subsequent degradation of polychlorinated biphenyls (PCB), are similar in structure but have different functions. The large subunit of BP Dox, encoded by the bphA1 gene, is crucial for substrate selectivity.

Isolation of Biphenyl and Polychlorinated Biphenyl-Degrading Bacteria and Their Degradation Pathway

Applied Biochemistry and Biotechnology, 2013
Four strains of biphenyl-degrading bacteria were isolated from a sewage and identified from the Rhodococcus genus (SK-1, SK-3, and SK-4) and Aquamicrobium genus (SK-2) by 16S rRNA sequence. Among these strains, strain SK-2 was most suitable for biphenyl degradation.

Polychlorinated biphenyls in the environment

Journal of Chromatography A, 1992
This review surveys the problems arising from the release of PCBs into the environment from the point of view of the analytical chemist. These problems are very complex and interdependent and so it is essential to recognize their mutual links rather than to separate one problem from another (sources of contamination, fate in the environment, toxic ...
