Alcoholic fermentation from grains with a noncooking system was successfully carried out on an industrial scale. It was found that an enzyme preparation from Rhizopus sp. was suitable for alcoholic fermentation with a noncooking system on an industrial scale. It was suggested that some enzymes, other than glucoamylase, (such as α-amylase and cellulase) were essential for alcoholic fermentation with noncooking.
