| Abstract: | The effect of oxidation products of shale kerogen (high-molecular-weight acids with 6–22 carbon atoms) on biodegradation of oil and oil products in soil and water was studied. High-molecular-weight acids (HMWA) not only affected the layer of oil and/or oil products and dispersed it into small particles, but also stimulated growth of Rhodococcus erythropolis VKM AS-1339D, degraders of oil and oil products. Addition of 0.001–0.003% HMWA to a medium to be purified from oil products increased the extent of bacterial biodegradation by a factor of 1.1–5.0. |
