The analysis of the selective influence of environmental factors such as humidity, temperature, pH, oxygen concentration, solar radiation indicates that the development of yeasts is determined by these factors. The purpose of the study was to determine influence of nitrogen sources, sugars, alcohols, primary acidity of the medium and temperature on the development of strains of yeast species Saccharomyces ellipsoideus. Results indicated, that for strains CH 57, CH 57g, CH 57k, AS 74, LE 38, LE 38c, YR 56, BA 82 and BA 83 of yeasts Saccharomyces ellipsoideus the best source of carbon and energy from sugar is glucose, from alcohols sorbit and mannit. For these strains the best source of inorganic nitrogen is (NH4)2SO4. All strains also good assimilated peptone as a source of organic nitrogen. The optimal temperature for these strains is 25°C, and the optimum acidity is pH 7,0.
