Abstract:
To obtain the best producing tannase medium and culture conditions, three key factors influencing the tannase production in solid fermentation were determined by single factor experimen and then response surface methods were applied., Results showed that the optimum conditions for the solid fermentation by Aspergillus niger were: gallnut content 9%; nitrogen source 2.3% and temperature 32 ℃, under which the enzyme activity was 219.4 U/mL.
