文摘

The consortium of thermotolerant petroleum-oxidizing bacteria containing strains Gordonia sp. 1D VKM Ac-2720 D, Rhodococcus sp. Par7 VKM Ac-2722 D, and R. pyridinivorans L5A-BSU VKM Ac-2721 for destruction of oil and oil products in hot climates was developed for the first time. The consortium was effective in soils and liquid media at temperature as high as 50°C, at salinity up to 7%, and soil moisture of about 10%. The efficiency of petroleum destruction for 21 days was 70 and 59% at 24 and 45°C, respectively. The consortium of thermotolerant petroleum-destructing strains could be used as basis for the biopreparation for remediation of petroleum-contaminated soils and waters in hot climates.
