A fermentable sugar feed is continuously converted by fermentation to dilute aqueous ethanol ("beer") in a series of agitated fermentation vessels which contain progressively more ethanol and less fermentable sugar. At least two strains of yeast are selected for the fermentation, one of which provides a high rate of ethanol production in a fermentation medium containing a relatively low concentration of ethanol and a relatively high concentration of fermentable sugar and the other of which provides a high rate of ethanol production in a fermentation medium containing a relatively high concentration of ethanol and a relatively low concentration of fermentable sugar.

A carbohydrate polymer such as starch and/or cellulose is converted to ethanol by a process in which an aqueous slurry of the carbohydrate polymer acid hydrolyzed to provide a sterile fermentable sugar solution is thereafter continuously converted by fermentation to dilute aqueous ethanol ("beer") in a series of agitated fermentations vessels which contain progressively more ethanol and less fermentable sugar employing at least two strains of yeast for the fermentation, one of which provides a high rate of ethanol production in a fermentation medium containing a relatively low concentration of ethanol and a relatively high concentration of fermentable sugar and the other of which provides a high rate of ethanol production in a fermentation medium containing a relatively high concentration of ethanol and a relatively low concentration of fermentable sugar.

Starch is recovered from an amylaceous material such as manioc root or corn in the form of an aqueous slurry containing substantially all of the soluble components, e. g. , carbohydrates and proteins, of the amylaceous material prior to processing. To accomplish such recovery, amylaceous material is milled in one or more steps in the presence of water to provide a slurry containing liberated starch particles and non-starch components. The initial aqueous starch slurry is then concentrated by removal of water therefrom. The water removed from the initial starch slurry contains soluble elements of the starch and is recycled to restore these elements to the starch recovery system.

Starch derived from dry milled corn is hydrolyzed to provide a sterile aqueous fermentable sugar solution which is especially adapted for fermentative conversion to ethanol with minimum thermal expenditure. Following an initial mild hydrolysis to thin, or liquefy, the starch, substantially all of the water insoluble protein and oil components, and a portion of the water soluble components, e. g. , sugars, lipids, proteins and vitamins, are separately recovered from the partial starch hydrolysate with the water solubles being recycled to the system. Thereafter, the partial starch hydrolysate is subjected to further hydrolysis to provide an aqueous solution of fermentable sugar.

Substantially anhydrous, i. e. , absolute, ethanol is distilled at high thermal efficiency from a dilute feedstock such as a fermentate ("beer") containing one or more low boiling components whose removal at least in part prior to anhydrous distillation is necessary in order to achieve an acceptable degree of phase separation in a decanter. Most of the low boiling component(s) are removed from the feed in a rectifying column with the balance of the low boiling component(s), insufficient in amount to seriously interfere with proper operation of the decanter, being removed from the system employing a light-ends column. Both the anhydrous column and the light-ends column are operated at substantially superatmospheric pressure with thermal values recovered from these columns being used in the operation of the rectifying column.

Water soluble oxygenated hydrocarbons produced by microbial fermentation, e. g. , ethanol, butanol, acetone, etc. , are conveniently and economically recovered with a minimum expenditure of energy by passing heated by-product carbon dioxide gas through at least a portion of the fermentation medium to simultaneously vaporize and carry off oxygenated hydrocarbon fermentation product dissolved therein and reduce the temperature of the fermentation medium to a level conducive to maximum oxygenated hydrocarbon production. The vaporized oxygenated hydrocarbon fermentation product is separated from the carbon dioxide gas in a scrubbing unit and the resulting aqueous solution of product is concentrated, if desired, by distillation.

An aqueous starch slurry is initially hydrolyzed in the presence of acid or enzyme and thereafter, the liquefied starch is saccharified in the presence of an acid cationic exchange resin to provide a sterile aqueous solution containing at least about 60 weight percent fermentable sugar based on the weight of the original starch present.
