The experiments for alcoholic fermentations by the use of fungal amylase method were carried out at the scale of pilot plants, using 2 koku (360 L) and 40 koku (7200 L) amylo-fermentors slightly improved for this process. The strain of Asp. niger spec. (ロIP) only was used for the preparation of fungal amylase.1) The conditions of submerged culture for the preparation of fungal amylase in 2 koku fermentor were as follow. Rate of air volume to the volume of mash was 25% per minute, and agitation was 100 r.p.m.. Under these conditions, satisfactory results were obtained.2) In case of 40 koku fermentor the rate of air volume to the volume of mash was 3% per minute, and agitation was 40 r.p.m.. The production of amylase in submerged mold culture was unsatisfactory.3) Adding submerged mold culture to the mashes, several runs of alcoholic fermentation were investigated and met with slightly good results, but it was defect of this method that the time of fermentation was too long.
