Fig. 4From: Synergistic effects of multiple enzymes from industrial Aspergillus niger strain O1 on starch saccharificationSynergistic effects of each enzyme component in glucoamylases cocktail on starch saccharification. a The effect of O1-1 neutral α-amylase on glucoamylases cocktail for starch saccharification. b The effect of O1-3 acid α-amylase on glucoamylases cocktail for starch saccharification. c The effect of the ratio of two glucoamylases on glucoamylases cocktail for starch saccharification. Values are means ± SD (n = 3 repeats). *P < 0.05 (Student’s t-test), n.s. not significantBack to article page
