A biosorbent containing an association of oil-oxidizing bacteria as the main constituent was developed, in which Lessorb, a product of moss and wood thermal processing, was used as a carrier. Xeroprotectors preserving the cell viability and oil-oxidizing activity in the biosorbent on drying and after long-term storage were selected. The use of this biosorbent for cleaning oil-polluted sod-podzol soils showed a two- to threefold cleanup rate acceleration at different pollution levels (8 and 24 l/m2), especially in the presence of a nitrogen–phosphate fertilizer. The biosorbent increased the populations of certain groups of soil microorganisms and the total soil biological activity.
