Optimization of the purification of soil and water objects from oil using biosorbents

Oil biosorbents (patents 2299181, 2318736) were obtained using immobilization of oil-oxidizing microorganisms into the hydrophobic sorbent Sorbonaft, which is manufactured using special technology at the Press-Torf Company. Two associations of aboriginal hydrocarbon-oxidizing microorganisms were used for this purpose: a fungal association and a bacterial and yeast association. The application of biosorbents resulted in a substantial acceleration of the process of purification from oil. The decrease in the amount of oil in the water and soil during 1 month was 30–44% in the variants with the products, against 5% in the control.
