Considering the cost-effectiveness of bioethanol production, there is a need for a yeast strain which can convert
glucose and xylose into ethanol at elevated temperatures. We succeeded in isolating a yeast strain, designated
strain ATY839, which was capable of ethanolic fermentation at temperatures above those previously reported for
yeasts able to ferment both glucose and xylose. Strain ATY839 was capable of producing a substantial amount of
ethanol at up to 37°C from 2% glucose or 2% xylose
