title: [Destruction of mixture of tri-hexa-chlorinated biphenyls by Rhodococcus genus strains].
abstract: Destruction of polychlorinated biphenyls (PCBs) by strain-destructors Rhodococcus sp. B7a and Rhodococcus sp. G12a has been studied. It was shown that these strains destruct 78-95% of PCB mixture containing tri-hexa-chlorinated biphenyls. Rhodococcus destruct all components of the mixture of tri-, tetra-, penta-, and hexa-chlorinated biphenyls without accumulation of toxic chlorinated metabolites. The studied bacteria destruct PCB that are the most stable for oxidation, such as 2,5,2',5'-CB; 3,4,3',4'-CB; and 2,4,5,2',4',5'-CB. The most perspective strains are R. rubber P25, Rhodococcus sp. B7a and Rhodococcus sp. G12a whose metabolic potential can be used for biotechnological refinement of the environment from highly toxic pollutants.
