The Influence of Ethanol and Temperature on Yeast Growth.Peer-reviewed article

Z. CIESAROVÁ, D. ŠMOGROVIČOVÁ

Changes of growth rate of 18 Saccharomyces cerevisiae yeast strains after extracellular ethanol addition and after fermentation under increased temperature respectively were studied. Combined effect of ethanol (6 % v/v) and temperature (35 °C) resulted in 60 % decrease of biomass acquisition. On the other hand, ethanol only in concentration 6-9 % v/v at 28 °C stimulated yeast growth rate. Small increase of temperature (from 28 °C to 33-35 °C) in earlier growth phases positively affected growth rate and ethanol production.
