[Effect of shale kerogen oxidation products on biodegradation of petroleum and petroleum products in soil and water]. / Vliianie produktov okisleniia kerogena slantsev na biodestruktsiiu nefti i nefteproduktov v pochve i vode.

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.

[A new oil-oxidizing micromycete Fusarium sp]. / Novyi nefteokisliaiushchii mikromitset Fusarium sp.

The strain Fusarium sp. No. 56 isolated from natural oil-containing soil samples taken near the city of Oktyabr'skii, Republic of Bashkortostan, displayed a pronounced capability of biotransforming oil and its light and heavy fractions. This micromycete is nonpathogenic and can grow at 10 degrees C. The latter property is of practical significance for its uses in soil and water bioremediation under cold climatic conditions of Bashkortostan and other regions.
