Abstract
An aqueous starch slurry is hydrolyzed in sequential liquefication and saccharification steps to provide saccharified starch containing from about 60 to about 80 weight percent of fermentable sugar based on the weight of the original starch present. Further saccharification is carried out either in one or more fermentation vessels wherein conversion of the sugar to ethanol simultaneously takes place or in one or more additional saccharification vessels.
