The effect of temperature on the kinetics of ethanol production by a thermotolerant strain of Kluveromyces marxianus

The batch fermentation kinetics of a novel thermotolerant strain of the yeast Kluveromyces marxianus were evaluated between 30 degree C and 48 degree C. The most significant effects of elevated temperature were reductions in overall biomass and ethanol yields. Decreases in the concentration of ethan...

Zusammenfassung:	The batch fermentation kinetics of a novel thermotolerant strain of the yeast Kluveromyces marxianus were evaluated between 30 degree C and 48 degree C. The most significant effects of elevated temperature were reductions in overall biomass and ethanol yields. Decreases in the concentration of ethanol attained, and the presence of unutilized substrate suggested increases ethanol inhibition at the higher temperatures studied.
