Abstract
As a result of the study, the best viability of monocultures and associations under freeze drying has been determined. The best two protective media during storage and their composition are the following: media No.1 includes (%) sodium acetate - 2.5; sodium citrate - 2.5; sucrose - 10.0; and protective media No.2 containштп (%) sucrose 8.0; gelatin - 1.5; skim milk - 5.0. Thus the titer of bacteria equaled to values of 6.0x1010 and 4.2x1010 CFU / g, respectively.
When determining the stability of dried preparations during storage of probiotic bacteria and their association, the best protective medium is No. 2 (sucrose 8.0%; gelatin - 1.5%; skim milk - 5.0%).
The antagonistic activity of monocultures (lactic acid bacteria Lactobacillus plantarum1, Streptococcus salivarius 20n, Lactobacillus fermentum 15, propionic acid bacteria Propionibacterium shermanii 34) and associations based on these monocultures is preserved practically at the initial level upon freeze drying.
A probiotic based on lactic acid and propionic acid bacteria can be used as a therapeutic and prophylactic agent against dyspepsia for farm animals. At the same time, there is no need for the use of antibiotics and other antibacterial agents for the treatment of diseased animals.
