FIELD: biotechnological methods for oil pollution removal. SUBSTANCE: bacterial strain isolated from soil polluted by petroleum derivatives is cultured for 72 h in liquid nutrient medium containing mineral salts, soya been flour, and molasses at pH 6.8-7.2 and 28 C under aerobic conditions. Destructive activity of preparation containing thus grown strain with regard to bicyclic and polycyclic mazut aromatics ranges between 84.9 and 93.6% (bicyclic) and between 90.1 and 93.1% (polycyclic) within a wide temperature range 15-25 C and a wide pH range: from 5.0 to 8.0. EFFECT: enhanced oil destructive activity. 2 tbl, 2 ex
