Optimization of glucoamylase production by Aspergillus niger in solid-state fermentation



Optimization of glucoamylase production by Aspergillus niger in solid-state fermentation



Applied Biochemistry and Biotechnology 128(2): 131-140



Glucoamylase production by Aspergillus niger in solid-state fermentation was optimized using factorial design and response surface techniques. The variables evaluated were pH and bed thickness in tray, having as response enzyme production and productivity. The bed thickness in tray was the most significant variable for both responses. The highest values for glucoamylase production occurred using pH 4.5 and bed thickness in the inferior limits at 2.0-4.2 cm.
