DESIGN OF A CONSORTIUM OF THERMOTOLE¬RANT BACTERIA AS A BASIS FOR A BIOPREPARATION TO REMEDIATE OIL-CONTAMINATED SOILS AND WATER ON TERRITORIES WITH HOT CLIMATE

Abstract

For the first time, the bacterial consortium consisting of thermotolerant oil-destructing strains of Gordonia sp. 1D VKM Ac-2720 D, Rhodococcus sp. Par7 VKM Ac-2722 D and R. pyridinivorans L5A-BSU VKM Ac-2721 D for the petroleum dest-ruction in soils and water in the hot climate regions has been de-signed. The consortium is effective in soils and water at the tem-peratures up to 50°C, medium salinity up to 7% and humidity about 10%. For instance, the efficiency of the oil degradation in model soil was 70% and 59% for 21 days at 24°C and 45°C, res-pectively. The association of the thermotolerant oil degrader strains can be used as a basis for a biopreparation for remediation of oil-polluted soils and water in the hot climate regions.
