Relations between elevated temperatures and fermentation behaviour of Kloeckera apiculata and Saccharomyces cerevisiae associated with winemaking in mixed cultures

One of the important factors affecting wine fermentation is temperature. The influence of elevated temperatures from 10 to 25 °C at 5 °C intervals on yeast growth and fermentation products were studied in mixed cultures of Kloeckera apiculata and Saccharomyces cerevisiae in grape juice. In the experiments carried out at 10 and 15 °C, K. apiculata grew and survived longer compared to trials conducted above 20 °C. In most cases, higher temperatures stimulated the production of higher alcohols but lowered the formation of esters and acetaldehyde.
