Abstract
The ionic composition of the of the intracellular content of the alcohol yeast Saccharomyces cerevisiae R. 1039 biomass was studied for confirmation of their use perspectiveness as a mediator to enable the management the mineral content of food in the manufacture of food and feed additives. The ionic composition of the obtained extracts were identified using the method of capillary electrophoresis. It is found that the quantitative ion content in the cell extracts depends on the concentration of the nutrient medium. When the yeast S. cerevisiae R. 1039 was cultivated on the medium with the soluble solids concentration of 30%, the intracellular ion content in the extracts was 1.3 times higher than when the yeast was cultivated on 12% wort by increasing the concentration of chlorides, sulfates, formates, potassium ions, and calcium. The yield of the yeast S. cerevisiae R. 1039 biomass increased 1.6 times per unit of volume of the medium with increase of the soluble solids concentrations from 12% to 30%.
