BIOHYBRID MATERIAL FOR SORPTION AND DEGRADATION OF OIL AND OIL PRODUCTS Russian patent published in 2013 - IPC B01J20/02 B01J20/22 B01J20/26 C12N11/04 C02F1/28 C02F3/32 C02F3/34 

FIELD: process engineering.

SUBSTANCE: invention relates to biotechnology and may be used for wasteless cleaning of water and solid surfaces from oil and oil product outflow. Proposed material comprises outer layer of polyester fibers and mid layer of polypropylene fibers comprising incorporated phosphorus-containing cationites and/or nitrogen-containing anionites, cell walls of hydrophytes and immobilised cells of oil destruction bacteria. Proposed biohybrid material features sorption capacity of, at least, 25 g/g of sorbent and degree of bacteria cell load of, at least, 150 mg/m² and may be used may times: at least, 5 regeneration cycles with extraction of, at least, 90% of sorbate in first cycle.

EFFECT: wasteless cleaning of water and solid surfaces from oil and oil product outflow.
