The authors cultured Asp. kawachii and its mutant on rice and PFEFFER's solution containing 5% glucose as carbon source (1% CaCO_3 added), in order to examine the production of organic acid, amylase and maltase by these molds, and they found the following facts.1) In contrast to the case of culture in the modified NAGELI's solution, the organic acids produced on the rice culture were of the same kind in the parent strain and the mutant.2) Vitamin B complex (oryzanin ex.) exerted no influence on the production of organic acids in the modified NAGELI's solution.3) The amylolytic enzyme in the mycelium of Asp. kawachii mutant M. 3. grown in PFEFFER's solution is composed of α-amylase and maltase, while β-amylase is set free in the culture solution.
