Using the pilot plants (1 and 2) previously reported, high-heap aeration process was conducted with wheat bran as main raw material. Aspergillus oryzae, Asp. niger and Bacillus amylosolvens were emplyed in producing hydrolyzing enzymes for various purposes. Chopping the culture medium into finger-shaped masses was necessary to reduce the pressure drop of air passing through the heap. Change in the direction of air flow and the areation rate were controlled automatically in response to the heap temperatures. The effects of temperature and moisture content upon enzyme formation were preliminarily investigated. The time-course of metabolism, heat evolution and enzyme formation in these pilot plant cultures were followed and the results were shown to be satisfactory in comparison with those obtained with ordinary tray methods.
