FIELD: biotechnology.
SUBSTANCE: method for obtaining biological product for biodegradation of organic bottom sediments which includes immobilization of microorganisms on an adsorbent carrier by mixing the material of the adsorbent carrier with a culture of microorganisms, treatment with a solution of mineral salts and glucose to form 3-10 mm granules, followed by curing at a temperature of 20-30°C. As an adsorbent-carrier, a mixture of powders of iron ore concentrate and decaying steel-smelting slag with a particle size of 0.3-1.0 mm is used at a mass ratio of these components of 1:0.5, processed under the influence of a constant magnetic field to achieve a residual magnetic induction of 0.3-1 mT.
EFFECT: invention provides expansion of the arsenal of methods for microbiological restoration of open water areas, coastlines contaminated with oil products and organic sediments.
