摘要: Alcohol fermentation of corn starch without cooking was performed by using Chalara paradoxa glucoamylase preparation, which had stronger raw digesting activity than those the conventionally known glucoamylases. A starch-enzyme-yeast mixture fermented optimally at pH 5.0 and 30 degrees C for five days produced ethanol. The yields ethanol were between 63.5 86.8% theoretical value baker's yeast (Saccharomyces cerevisiae), 81.1 92.1% sake sake).
