METHOD TO PRODUCE PROBIOTIC PREPARATION BASED ON SPOROGENOUS STRAINS Bac subtillis AND Bac licheniformis Russian patent published in 2011 - IPC C12N1/20 A23K1/165 C12R1/07 

FIELD: agriculture.

SUBSTANCE: method to produce a probiotic preparation based on sporogenous strains Bac.subtilis and Bac.licheniformis includes their cultivation, mixing of bacterial cells biomasses with protector of microbial cells and subsequent sterile dehydration. At the same time the method uses the strain Bac. subtilis VKPM V-10172 and the strain licheniformis VPKM V-10135. Biomasses of strains are mixed at the ratio of 1:1. A protector of microbial cells is a gelatine-saccharose protective medium in amount that provides for cell titre in the finished product after drying of at least 2X1012 CFU/g.

EFFECT: method makes it possible to produce a preparation with high efficiency of probiotic component, which ensures higher digestibility of fodders and increases weight gain of farm animals and birds.
