Consortium of Bacteria as a Basis for Creating Probiotic Additives for Livestock Production

Abstract

Currently, one of the conditions for the intensification of animal husbandry in Russia is the application of the concept of rational feeding of animals that require the application of complete feed ensuring optimum utilization of the genetic potential productivity of animals and to receive their quality products, safe in veterinary and sanitary relation. This article discusses information about the growing popularity of biological drugs for animal - probiotic supplementation to animal feeds with antibiotic substances of protein nature peptide - bacteriocins. Currently studying ways and means of directed synthesis of bacteriocins, with the aim of obtaining biologically different modifications of known bacteriocins, but with more valuable properties, or new natural balanced bacteriocinogenic complexes, safe to use as preservatives. The aim of this work is the design of a consortium of lactic and propionic acid bacteria with the highest production of bacteriocins production of additives for feed purposes. The work was carried out in VNIIPBT. In this study, we investigated antimicrobial activity of the selected probiotic strains, the dynamics of crop development Lactobacillus plantarum 578/25 and Propionibacterium freudenreichii subsp. shermanii VKM 103/27 investigated the feasibility and benefits of joint cultivation of microorganisms Lactоbacillus 578/25 plantarum and Propionibacterium freudenreichii subsp. shermanii VKM 103/27 along with their single cultivation. The experimental data on the joint cultivation of monocultures and the consortium confirmed the need for the stage of selection of bacterial cultures to create complex additives with probiotic properties, to improve the overall biosynthetic activity of the consortium. The research results are preliminary and will be supplemented with new experimental data in the subsequent work.
