METHOD FOR OBTAINING BIOLOGICAL PRODUCTS OF LIVING MICROORGANISMS WITH AN EXTENDED PERIOD OF PRESERVATION OF A HIGH TITER OF VIABLE CELLS BY IMMOBILIZATION IN GELS BASED ON SILANOL DERIVATIVES OF HUMIC SUBSTANCES

摘要

FIELD: biotechnology.;SUBSTANCE: invention relates to biotechnology and can be used to stabilize biological products containing live microorganisms. The method provides for the preparation of a gel from alkaline solutions of humic substances (HS) and 3-aminopropyltrialkoxysilane (APTS) by titration with an acetic acid solution to a pH value close to neutral, followed by the addition of APTS, immobilization of microorganism cells in gels by mixing a suspension of bacteria and gel in a given ratio, the stage of keeping for several hours until the gel thickens.;EFFECT: invention allows microorganisms being kept in an active state for a long time.;12 cl, 6 dwg, 1 tbl, 6 ex
