Abstract: Alcaligenes latus bacterial strain TXD-13 VKPM B 75-05 is capable of degrading polychlorinated biphenyls (PCBs). The strain may be employed to detoxicate environment media and PCB-containing industrial waste. To produce biomass, the strain is incubated on media which contain carbon sources, nitrogen sources and mineral salts. The strain is cultivated by a subsurface method up to a titer from 6.0·108 to 2.0×109 cells per cu cm. The produced biomass is used for degrading PCBs in concentrations from 107 to 108 cells per cu cm. The strain ensures from 35 to 50% reduction in PCB content in soil and water.
