A complex of biological characteristics important for design of the therapeutic and prophylactic activities of Bifidobacterium and Lactobacillus preparations made with the use of hydrolysate-milk and hydrolysate-soybean media was comparatively estimated. The use of the hydrolysate-soybean medium resulted in an increase of the antagonistic activity of the preparations against a number of opportunistic pathogens that was not connected with changing of their acidity and the content of lysozyme, a bacteriolytic enzyme in the culture fluid. The change in the cultivation conditions due to substitution of the hydrolysate-milk medium for the hydrolysate-soybean medium stimulated the adhesive capacity of the production strains used in the study, which was especially evident with respect to the representatives of the genus Bifidobacterium.
