Diversity of culturable aerobic bacteria isolated from lindane-contaminated soils

It was found that in the soils sampled on the territory of OJSC "Sredne-Volzhsky plant of chemicals" in Chapaevsk, Samara region in 2013, the concentration of lindane varies in the range of 0.393 - 53.449 mg / kg of soil. 26 strains of aerobic culturable bacteria were isolated from soils. It was shown that there is a direct correlation between the level of contamination of the soil sample with lindane and the number of isolated strains. The dominant position is occupied by representatives of the phylum Proteobacteria, classes α-, β- and γ-Proteobacteria. It was found that strains of Ochrobactrum sp. NE3 and Ochrobactrum sp. 132 decompose by-products of biotransformation of lindane (1,2,4-TCB and 2,5-DCP), and can be recommended for use in biotechnologies for remediation of lindane-contaminated soils to prevent the accumulation of hazardous compounds.
