A UV-induced mutant of Pichia stipitis with increased ethanol production from xylose and selection of a spontaneous mutant with increased ethanol tolerance
TL;DR: After continuous cultivation of Pichia stipitis NBRC1687 in YNB (yeast nitrogen base) medium containing 2% xylose and 5-7% ethanol, an ethanol-tolerant mutant, PET41, was obtained and might be thus useful for two-phase fermentation.

Ethanol production by repeated-batch simultaneous saccharification and fermentation (SSF) of alkali-treated rice straw using immobilized Saccharomyces cerevisiae cells.
TL;DR: The immobilizing carrier could be reused without disintegration or any negative effect on ethanol production ability, and the ethanol yields based on the glucan content of the immobilized cells were slightly low.

Isolation of a novel strain of Candida shehatae for ethanol production at elevated temperature
TL;DR: Strain ATY839 was capable of producing a substantial amount of ethanol at up to 37°C from 2% glucose or 2% xylose and is considered to be the most tolerant to high temperature of the C. shehatae strains.
Selection of stress-tolerant yeasts for simultaneous saccharification and fermentation (SSF) of very high gravity (VHG) potato mash to ethanol.

TL;DR: Osmotolerant yeasts from a collection of 1699 yeast strains at the institute found that three strains were candidates for use in bioethanol production and demonstrated the simultaneous saccharification and fermentation (SSF) of very high gravity (VHG) potato mash and sweet-potato mash.

A strategy to prevent the occurrence of Lactobacillus strains using lactate-tolerant yeast Candida glabrata in bioethanol production
TL;DR: The data show the possibility of designing an effective fuel ethanol production process that eliminates contamination by Lactobacillus strains through the combined use of lactate addition and C. glabrata.
