1) We studied on the submerged culture of mold in the pilot-plant tank used for the production of penicillin. As the aeration and agitation of the medium was very good, the activity of mold amylase was great. Adding 5% of this submerged mold culture and 20% of amylo-shubo to the main mashes, the alcohol yield was 88%. 2) Improving 40 koku fermentor like 1 koku fermentor, we succeeded in the production of the submerged mold culture, when air flow rate was 25% to the volume of mashes and agitation rate 100 r.p.m. Using this amylase preparation for the alcoholic fermentation, the yield of alcohol was 89%. 3) For this method, the strain of Asp. awamori spec.(NP 39) was most suitable and the best medium was composed as follows : corn 1%, wheat bran 3%, rice bran 2%, NaNO_3 0.1%, HCl (36%) 0.1%.
