BIORESTORATION METHOD FOR ACCELERATED BIOLOGICAL DECOMPOSITION OF PETROLEUM HYDROCARBONS IN SEA ICE-COVERED POLAR REGIONS, AND BACTERIA AND ENZYME MIXTURE AS AGENT FOR REALISING SAID METHOD Russian patent published in 2011 - IPC C02F3/34 C12N1/26 

FIELD: chemistry.

SUBSTANCE: invention relates to biotechnology. Method for biological decomposition of petroleum hydrocarbons in sea ice-covered polar regions involves contacting the petroleum hydrocarbons with an inoculum. The inoculum contains a mixture of cold-adapted bacteria consisting of at least the following strains: Rhodococcus GH-1 (DSM 18943, DSMZ 22.12.2006), Dietzia GH-2 (DSM 18944, DSMZ 22.12.2006), Shewanella GH-4 (DSM 18946, DSMZ 22.12.2006), Marinobacter GH-9 (DSM 18951, DSMZ 22.12.2006), Pseudomonas GH-10 (DSM 18952, DSMZ 22.12.2006), Oleispira GH-11 (DSM 18953, DSMZ 22.12.2006), as well as nutrients and at least one an environmentally friendly carrier material on which at least the said bacteria strains intended for use are immobilised.

EFFECT: invention increases efficiency of decomposition of petroleum hydrocarbons in sea ice-covered polar regions.
