摘要

The present invention provides in a process of producing ethanol from starch-containing material comprising: (a) saccharifying the starch-containing material; and (b) fermenting using a fermentation organism; wherein saccharification and/or fermentation is done in the presence of at least a glucoamyl ase and optionally an alpha-amylase; the fermenting organism is Saacaromyces cerevisiae; and wherein a glucoamylase and/or an alpha-amylase is expressed from the fermenting organism. Further the invention provides yeast strains specifically developed for the process of the invention.
