Abstract

|
|
Asp. oryzae D and H strains were cultured in the wheat bran and Czapek-Dox liquid media containing garlic powder in order to investigate the effect of garlic on the enzyme production and growth of Asp. oryzae. The results obtained were as follows;
1. Wheat bran media containing 0.5 to 2% garlic powder yielded increased in acid protease activity of the Asp. oryzae D strain while the best activity appeared at 2 to 6% in alkaline protease and 0.5% in neutral protease.
2. The protease activities of Asp. oryzae H strain was similar to that of the control in wheat bran media containing 0.5 to 8% garlic powder, but the peak appeared at the garlic powder concentration of 30%.
3. Garlic powder increased the α-and Glucoamylase activities of Asp. oryzae H strain. 4. Garlic powder inhibited the both Asp. oryzae strains from the cellulase production. 5. Gzapek-Dex liquid media containing 0.5 to 6% garlic powder yielded increase in dry mycerial weight in comparison with the control, and the increament was much more in case of the Asp. oryzae H strain.
6. As the amount of the garlic powder added to the Czapek-Dox liquid media increased, the pH of the cultured media of Asp. oryzae D strains was on the decrease while the media of H strain increased.
7. As the amount of the garlic powder added increased, the acidity of the cultured Czapek-Dex media increased.
8. The growth rate of the two Asp. oryzae strains were remarkably inhibited and no growth appeared in wheat bran and Czapek-Dox media containing garlic powder more over 10%.
9. The utility rate of reducing sugar was the highest in the Czapek-Dox liquid media containing 1 to 2% garlic powder.
