Fig. 6From: Optimization and partial purification of beta-galactosidase production by Aspergillus niger isolated from Brazilian soils using soybean residueThe effect of in vitro simulated fasted gastric (SGF) conditions on partially purified β-galactosidase. Control: enzyme incubated with buffer pH 2.0. Enzyme + SGF (NaCl 2%, bovine pepsin 0.32% and HCl 7%). *Indicates statistical difference in the ANOVA Tukey test with significance level (p < 0.05) between control and enzyme + SGFBack to article page
