3.1.1.20 | Aspergillus oryzae | addition of D-glucose over 0.5% (w/v) concentration represses enzyme production. Addition of NaCl, MnSO4 or CdSO4 leads to decreased rate of tannase production | down |
3.1.1.20 | Aspergillus japonicus | addition of MnSO4, ammonium molybdate, or CdSO4 leads to decreased rate of tannase production | down |
3.1.1.20 | Aspergillus japonicus | enzyme production is not induced by the addition of D-glucose (0.05-2% w/v) | additional information |
3.1.1.20 | Aspergillus oryzae | addition of 0.05-0.5% (w/v) D-glucose favors the synthesis of tannase. NH4Cl is the most suitable nitrogen source for maximal tannase production. CaCl2 stimulates tannase production most efficiently. Tannic acid is the most favorable source of tannin for maximal tannase production | up |
3.1.1.20 | Aspergillus japonicus | NH4Cl is the most suitable nitrogen source for maximal tannase production. CaCl2 stimulates tannase production most efficiently. Extract of China green tea is the best source of tannin for high tannase production | up |
