Screening of bacterial strains isolated from soils contaminated with organochlorine pesticides was carried out. Bacterial strains have been identified that are capable of growth on a mineral medium with organochlorine pesticides the γ-isomer of hexachlorocyclohexane and dichlorodiphenyltrichloroethane as the only carbon source. The processes of hexachlorocyclohexane degradation by monocultures and associations of isolated bacterial strains were studied. A monoculture of bacterial strains and a consortium created on the basis of the four most active strains are capable of destroying hexachlorocyclohexane when contained in a nutrient medium at a concentration of 100 μg/ml. It was shown that monocultures of four bacterial strains almost completely degraded hexachlorocyclohexane within one month. The consortium of destructor strains contributed to a decrease in the initial concentration of the drug from 100 μg to 45.55 μg in 12 days. The species identity of the active strains of destructor bacteria was determined.
