COMPLEX BIO-SORBENT ON BASE OF BACTERIA STRAIN AND FUNGI FOR PURIFICATION OF WATER MEDIUM FROM OIL AND OIL PRODUCTS AT PRESENCE OF MICRO-ALGA Russian patent published in 2011 - IPC E02B15/04 C02F3/32 C02F3/34 C12N1/26 

FIELD: oil and gas production.

SUBSTANCE: immobilisation on carrier of micro-organisms is performed by adsorptive procedure producing individual sorbents: bacterial with culture Rhodococcus eqvi P-72-00, yeast with culture Rhodotorula glutinis 2-4 M and fungi with filamentous fungi Trichoderma lignorum F-98. Also, complex bio-sorbent for purification contains a composition of individual sorbents at the following ratio of components, wt %: bacterial with culture Rhodococcus eqvi P-72-00 45-55; yeat with culture Rhodotorula glutinis 2-4 M 45-55, or bacterial with culture Rhodococcus eqvi P-72-00 45-55; fungi with filamentous fungi Trichoderma lignorum F-98 45-55, of bacterial with culture Rhodococcus eqvi P-72-00 40-50; yeast with culture Rhodotorula glutinis 2-4 M 20-35; fungi with filamentous fungi Trichoderma lignorum F-98 25-35. Bio-sorbent is applied together with concentrated culture of micro-alga Chlorella vulgaris Beijer at ratio of components for dry substance, wt %: bio-sorbent 90-97, bio-mass of micro-alga Chlorella vulgaris Beijer 3-10.

EFFECT: increased rate and completeness of bio-degradation of oil and toxic oil products; bio-sorbent for purification of water basins from oil and oil products, as sorbent, including hydrophobic oil sorbent on base of peat and oil-oxidising micro-organisms immobilised on carrier at effective amount.
