Probiotic lactobacteria for creation of selenium containing dietary

Abstract

The aim of the study was to select probiotic strains of Lactobacillus are capable of biotransformation of sodium selenite into nanoselen formation to create probiotic selenium containing dietary supplement for birds. Two strains of Lactobacillus casei IMB B-7280 and L.plantarum IMB B-7679, which are capable of transforming sodium selenite, were selected from the collection of probiotic cultures of the Department of Interferon and Immunomodulators. The selection of these strains of lactobacilli as producers of biogenic Nano-Se is due to their ability to transform sodium selenite and their ability to inhibit the reproduction of pathogenic and opportunistic microorganisms, increase the immune responses of the organism and their belonging to the category of Generally Recognized As Safe microorganisms. The ability of L.casei IIB B-7280 and L.plantarum IMB B-7679 to transform sodium selenite for synthesizing Nano-Se and other organic Se compounds which are suitable for making food additives makes it possible to consider Bacterial strains of Lactobacillus as a cheap source of organic Se and Nano-Se.
