FIELD: oil pollution removal. SUBSTANCE: soil is treated with bacterial culture adapted to petroleum hydrocarbons in mixture with biostimulant, the former being bacterial strain Bacillus sp. and the latter protein feed mixture prepared by biotechnological technique on the basis of hydrocarbon-containing raw material using non-pathogenic strains as producers. The two components of mixture are combined at 1:1 ratio. EFFECT: accelerated petroleum biodegradation process and increased degree of soil cleaning with no special equipment involved. 3 tbl
