In recent years, alcoholic fermentation has received much attention as an alternative energy source. In conventional alcoholic fermentation from starchy materials, precooking is necessary for liquefaction and saccharification of the broth, which requires a large amount of heat energy - about 30-40% of all energy spent for alcohol production. Ueda and his co-workers have attempted to produce ethanol from raw starch in a single-step process, which combines liquefaction, saccharification, and yeast fermentation without cooking and autoclaving by using glucoamylase preparation from Aspergillus niger in order to save the cost of energy consumption by cooking. Ueda has also reported alcoholic fermentation of sweet potato without cooking by using Rhizopus glucoamylase preparation. In the present communication, we report the effectiveness of alcoholic fermentation of sweet potato without cooking by using Endomycopsis fibuligers glucoamylase preparation. (Refs. 5).
