ABSTRACT:
Grain alcohol is produced from a mash of high cereal grain content by cooking a dispersion of cereal grains in water at a temperature of about 300.degree. to 350.degree. F under a pressure of about 50-120 psig, converting the cooked mash with a glucoamylase ferment produced by A. awamori NRRL 3112 and fermenting the converted mash with yeast to produce grain alcohol. The glucoamylase ferment is preferably produced by propagation of A. awamori NRRL 3112 on a mash of cereal grains dispersed in water which has been cooked at the same pressure and temperature used for cooking of the mash when producing grain alcohol.
