GRANULATED COMPOSITION CONTAINING MICROORGANISMS, METHOD OF ITS PREPARING AND USING Russian patent published in 2000 - IPC

FIELD: microbiology. SUBSTANCE: granulated composition involving finely dispersed substrate, polymeric layer containing microorganisms and water. Polymer is film-forming, water-soluble and practically noncrossed-linked polymer or film-forming cross-linked polysaccharide containing carboxyl groups and swelling in water in the presence of potassium ions. Composition has milled bran, straw, wood dust, cellulose, clay, attapulgit, kieselguhr, vermiculite and other substances as substrate. Composition has homopolymer or copolymer of polyvinyl alcohol, polyethylene glycol or polyvinylpyrrolidone, polyacrylamides, starch, carrageenan, alginate, xanthane, carob tree (Ceratonia siliqua) resin, methylcellulose as film-forming water-soluble polymer. Among microorganisms composition has Pseudomonas, Penicillin and others. Method of preparing the composition involves suspending polymer or polysaccharide and microorganism and spraying on the prepared suspension on finely dispersed substrate followed by water removal up to its content 0.5-40% in the composition. Prepared granulated composition containing microorganisms is stable at storage at the room temperature. EFFECT: improved method of preparing, high stability. 43 cl, 6 tbl
