摘要： Disclosed herein are yeast strains and derivatives thereof, as well as compositions comprising the yeast strains for use in ethanol manufacture. The disclosure also relates to processes for producing ethanol from biomass using the yeast strains and compositions. In particular, the yeast strains produce lower glycerol and higher ethanol, and have a higher temperature tolerance and higher fermentation rate than strains and products currently used in ethanol production processes.

摘要： The present invention relates to the field of fermentation, more particularly to ethanol production. Even more particularly the present invention relates to reduced aroma production during fermentation processes. The present invention provides mutant alleles and chimeric genes useful to develop yeast strains to limit acetate ester levels during fermentation. In addition, the invention also relates to the use of such yeast strains as well as of compounds for the production of fermented foods and liquids with reduced acetate ester levels.
