  • Strain of alcaligenes latus bacteria used for the decomposition of polychlorinated biphenyls
    Patent number: 6287842
    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.
    Type: Grant
    Filed: September 20, 2000
    Date of Patent: September 11, 2001
    Assignee: Research Center for Toxicology and Hygienic Regulatiom of Biopreparation
    Inventors: Nikolai Romanovich Dyadischev, Gennady Alekseevich Zharikov, Vladimir Vladimirovich Kapranov
  • Strain of Hansenulla californica yeast used for the decomposition of polychlorinated biphenyls
    Patent number: 6284521
    Abstract: Hansenulla californica yeast strain VKPM Y-2284 is capable of degrading polychlorinated biphenyls (PCBs). The strain may be employed to detoxicate environment media and PCB-containing industrial wastes. 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 5.0·106 to 1.0×107 cells per cu cm. The produced biomass is employed for degrading PCBs in concentrations from 106 to 105 cells per cu cm. The strain ensures from 30 to 50% reduction in PCB content in soil and water.
