Abstract

The article presents data on the positive impact of essential microelement selenium on the human body. The reasons which lets to deficite consumption of selenium microelement by human body has been described. It was characterized the ability to accumulate inorganic forms of selenium (selenites, selenates) by probiotic microorganisms and turning its into organic forms. The results which describes impact of different concentrations sodium selenite into the biomass growth of Lactobacillus acidophilus (MRS broth) and Bifidobacterium bifidum (on the medium with addition soya extract) has been obtained. During experimental work the values of optical density biomass cultures of Lactobacillus acidophilus and Bifidobacterium bifidum during the cultivation on the mediums with addition of various concentrations of selenite sodium were obtained. The obtained data defined specific growth rate and the duration of generation of Lactobacillus acidophilus culture and Bifidobacterium bifidum culture. The optimum concentrations of sodium selenite for cultivation microorganisms and concentrations of sodium selenite which causes inhibition of biomass growth were defined.
