Abstract: The present invention relates to processes for producing ethanol from starch-containing material using a Saccharomyces cerevisiae yeast deposited under Accession No. V15/004035, V15/004036 or V15/004037 at National Measurement Institute, Victoria, Australia) or a fermenting organism strain having properties that are about the same as that of the deposited Saccharomyces cerevisiae strain or a derivative of Saccharomyces strain V15/004035, V15/004036 or V15/004037 having the defining characteristics of strain V15/004035, V15/004036 or V15/004037. The invention also relates to Saccharomyces yeast deposited under the Budapest Treaty and having NMI accession no. V15/004035, V15/004036 or V15/004037 or a derivative of strain V15/004035, V15/004036 or V15/004037 which exhibits one or more properties or defining characteristics of strain V15/004035, V15/004036 or V15/004037. The invention also relates to compositions comprising a Saccharomyces yeast of the invention and naturally occurring and/or non-naturally occurring components.

Abstract: The invention relates to improved processes of producing ethanol from starch-containing material wherein saccharification and/or fermentation is done at a temperature below the initial gelatinization temperature in the presence of glucoamylase and alpha-amylase, and optionally a protease and/or a cellulolytic enzyme composition; wherein the fermenting organism is a Saccharomyces yeast strain providing a higher ethanol yield boost and lower glycerol production compared to ETHANOL RED™ under the same fermentation conditions. The invention also relates to Saccharomyces yeast strains and derivatives thereof, as well as compositions comprising such yeast strains, suitable for use in a process of the invention.
