FIELD: chemistry.
SUBSTANCE: invention relates to biotechnology and methods of cleaning soil and the surface of solid objects from petroleum and petroleum products. The method involves treatment of the contaminated object with a microbial preparation consisting of a mixture of natural hydrocarbon-oxidising cultures of microorganisms isolated through selection from a natural biocenosis of microorganisms. The preparation used is based on a biocenosis of microorganisms inhabiting sea brown algae of at least one genus, and the treated object is further treated with water and a biogeneous additive.
EFFECT: invention increases the rate and efficiency of cleaning solid objects from petroleum and petroleum products even with high salt concentration and relatively low temperature, including in regions with a short warm period.
