The writer cultured 11 strains of Apergillus on rice bran and mixture of soybean meal and bran in proportion of 7 : 3,and investigated about the production of analyse and protase. The amylase of the strain "long" of Aspergillus Oryzae was strong in every culture, but that of the straiin "short" full behind. As for 2 strains belonging to the Aspergillus niger group amylase produced in rice culture was quite weak, while that produced in cultures on rice bran or its mixture with soybean meal was remarkably strong. Casein is digested by the strain "short" of Aspergillus Oryzae somewhat stronger than the strain "long". By using autolysate of the strain "long", however, its proteolytic action was sometimes strong. Particullarly noticeble was the protease of black Koji much stronger than generally supposed.
