title: [Limiting the growth of Saccharomyces serevisiae yeasts under chemostat conditions by carbon and nitrogen sources].
abstract: Chemostat Saccharomyces cerevisiae cultures were obtained at D = 0.066 h-1 and growth limitation with ethanol and a nitrogen source with similar population densities. The threshold concentration of ethanol was 0.1 g/L and that of nitrogen 0.014 g/L. The optimal specific load of ethanol was 2.5--3.5 g/g biomass per hour with the economic coefficient of 40%. At the constant specific ethanol load, the economic coefficient changed at different rates of flow. The cultures differed in the content and amino acid composition of protein.
