Degradation of Benzpyrene by soil Microorganisms in the Presence of Glycolipids Produced by Strain Pseudomonas sp. Ps-17
The data on degradation of benzpyrene (BP) by soil microorganisms in the presence of ramnolipids that are produced by strain Pseudomonas sp. PS-17 are represented. In a model experiment, a soil extract with BP in a concentration of 100 mg/l and a ramnolipid as a chloroform-methanol (2:1) extract of supernatant of Pseudomonas culture liquid was investigated. The experiment lasted for 60 days. It was established that ramnolipids increased the degree of BP degradation by 18% as compared to control (82% versus 64%). A high stability of BP in sterilized soil testifies to the fact that its degradation is a biological process.
