This experiment was conducted to study on the productive conditions of cellulase by Aspergillus saitoi in the shaking culture medium. The results were as follows: 1. The production of enzyme required higher concentration of corn steep liquor than that of dextrin. 2. The concentration of 1.0% $NH_4H_2SO_4$ produced the enzyme excellently than 3.0%. 3. The cellulase was produced very slowly by adding $(NH_4)_2SO_4$, but the final concentration of the enzyme was higher than control. The production was suppressed by addition of $CaCO_3$. 4. The addition of $1.0{\sim}2.0%$ substrate caused an increase or stimulation in cellulase production.
