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.

Abstract: The present invention relates to processes for producing ethanol from starch-containing material by liquefying the starch-containing material at a temperature above the initial gelatinization temperature using an alpha-amylase; saccharifying using a glucoamylase and fermenting using a Saccharomyces cerevisiae yeast strain deposited under Accession No. V14/004037 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 V14/004037 having the defining characteristics of strain V14/004037. The invention also relates to a Saccharomyces yeast strain deposited under the Budapest Treaty and having NMI accession no. V14/004037 or a derivative of strain V14/004037 which exhibits one or more defining characteristics of strain V14/004037. The invention also relates to a process of recovering/extracting oil from an ethanol process of the invention using a Saccharomyces strain of the invention and compositions comprising a Saccharomyces yeast strain of the invention and naturally occurring and/or non-naturally occurring components.

Abstract: The present invention relates to methods for producing Saccharomyces strains that are capable of growth on xylose as a sole carbon source at a desired growth rate, (such as at least one generation per 48 hours), strains made by such methods, and Saccharomyces strains that grow at a growth rate of at least one generation per 48 hours using xylose as a sole carbon source for growth made by non-recombinant methods.
