Formation of the bacterial community as the basis of probiotic supplement for livestock

Abstract

The paper presents the results of research on the creation of a community based on lactobacilli and bacilli with antimicrobial activity against pathogens of intestinal infections in farm animals. B. subtilis strain MP 2 and L. plantarum strain MP 5 included in the consortium are characterized by resistance to artificial gastric juice and bile salts, as well as the ability to form extracellular hydrolytic enzymes (xylanase, carboxymethylcellulase, avicelase, β-glucosidase, amylase, phytase, protease and lipase), antimicrobial (acids, bacteriocins, siderophores and exopolysaccharides) and antioxidant metabolites. B. subtilis strain MP 2 and L. plantarum strain MP 5 did not have hemolytic activity and did not carry genes responsible for toxin production, which indicates the potential safety of this bacteria. It was concluded that the developed consortium is promising for use as a probiotic for animal husbandry.
