Abstract

Food products of functional purposes, where nutritional supplements have a special position, have a positive physiological effect on human health by affecting the digestive tract. In the present research article, there are results of experiments on selection of microorganisms for making a nutritional supplement with probiotic properties. The nutritional supplement is to contain specially chosen and identified strains, including Lactobacillus, Bifidobacterium, Streptococcus salivarius subsp. Thermophilus. The microorganisms are identified by their physiological, biochemical and genetical properties and are deposited in Federal Institution “State Research Institute of Genetics and Selection of Industrial Microorganisms of the National Research Center” Kurchatov Institute” – GosNIIGenetika. The authors present results of experimental work on combinability of the strains with each other based on the method of coculturing of examined strains and with filter liquors of other strains. It is proved that the strains of probiotic bacteria enter into symbiotic relationship with each other as well as with the examined technologic strain of Streptococcus thermophiles. The experimental results of antagonistic activity of a supplement made on the basis of examined strains give evidence of a marked antagonism to the testing cultures of microorganisms that can cause intestinal infectious diseases. The conducted research made it possible to produce a nutritional supplement with probiotic properties that can be recommended to use in functional food product technology.
