Title: Fuel ethanol from raw corn

Abstract

Crude amylase preparations were produced by growing Aspergillus awamori and A. niger on raw ground whole corn. These Koji preparations were used to hydrolyze the starch of raw ground whole corn to sugars during simultaneous fermentation of the sugars to ethanol by distillers active dry yeast. Ethanol concentrations of the fermentation beers were determined with gas-chromatography. These fermentations yielded an average of 89.6% theoretical ethanol compared to control, conventional, fermentations that had an average of 89.8%. Carbon dioxide evolutions were determined with use of Alwood valves. Both the Koji and conventional fermentations produced an average of 0.48 gram of carbon dioxide per gram of dry substrate starch within 72 hours. However, initially the conventional fermentation rate was greater. Koji dehydrated at 41/sup 0/C had no apparent detrimental effects on theoretical ethanol yield.
