Antagonistic activity research of the combined inoculum on the basis of microbial association of kefir grains

This article presents data on the antagonistic activity of the microbial consortium. The chemical composition of the natural mineral water is used to obtain microbial cells. It provides a high activity and stability of lactose fermenting yeast cells. The conducted research proves the antibiotic activity of the microbial consortium on the basis of cultures of lactose fermenting yeasts allocated from the TransBaikal ecosystems, microbial associations of kefir grains and Lactobacillus acidophilus. The developed ratio of cultures provides its resistance to potentially pathogenic microflora (E.coli). E.coli strain is used as test culture for determination of antagonistic activity of microbic consortium. It is known that enrichment of foodstuff by functional component is performed due to introduction of biocomponents of an animal and vegetable origin in foodstuff composition, and also fermentation process. The received microbic consortium has big practical application in the field of functional food.
