A biopreparation inducing oil destruction and increasing the biological activity of soils was developed on the basis of activated sludge. Its oxidative activity towards hydrocarbons was studied. The application of this biopreparation to oil-contaminated soil increased the population density of microorganisms, including destroyers of hydrocarbons, and accelerated oil decomposition. The degree of destruction of oil and oil products in the case of a single treatment of the soil with this biopreparation comprised 30 to 50% within 60 days. The presence of cellulose-decomposing microorganisms in this biopreparation also favored an accelerated decomposition of plant substances, including plant litter and sawdust applied to the urban soils as an adsorbent.
