[Toxic and mutagenic influence of hexachlorocyclohexane and its microbial destruction products on soil microbial cenosis].
Microbial strains Pseudomonas putida 9, Stenotrophomonas maltophilia IMV B-7288 destructed hexachlorcyclohexane (HCH) isomers complex by 31.1-76.6 and 30.7-73.2%. respectively, in comparison with given level. HCH and its destruction intermediates had toxic and mutagenic influence on soil microbial associations decreasing their survival to 6.9-21.7%. The investigated destruction products and intermediates obtained by Pseudomonas putida 9, Stenotrophomonas maltophilia IMV B-7288 have demonstrated weak mutagenic properties. The use of cultures-destructors opens the prospects for application of the mentioned strains as the components of microbial biopreparations for remediation of polluted soils. The use of soil microbial cenosis as the test-system for ecotoxicological assessment permitted to obtain more detailed pattern of toxic and mutagenic properties of HCH and products of its destruction.
