Utilization of oil in soil and water by microbial cells

Abstract

Pure cultures and culture associations actively utilizing aliphatic and aromatic fractions of oil of the Romashkinskoe oil field were selected. Biopreparations based on vermiculite-immobilized active oil-degrading strains were developed. The ability of the preparations to decompose oil in soil and water was shown. The preparation containing an association of yeast and the bacterium Acinetobacter sp. 725 proved most efficient. In field lysimetric experiments, the introduction of the preparations accelerated oil decomposition by up to 65-78% compared to the control. 6 refs., 2 figs., 4 tabs.
