Production of Aspergillus niger GH1 tannase using solid-state fermentation
Cruz-Hernandez, M. A.; Contreras, J. C.; Lima, Nelson; Teixeira, J. A.; Aguilar, Cristóbal N.The production of tannase by Aspergillus niger GH1 in solid-state fermentation (SSF) was evaluated. Several concentrations of tannic acid (12.5, 25, 50 and 100 g/L) were tested in a model culture system. Column reactors were packed with polyurethane foam impregnated with liquid medium and inoculated with fungal spores. Tannase production was kinetically monitored by 48 h. Tannic acid uptake was spectrophotometr...
