Figure 3From: Secretion and properties of a hybrid Kluyveromyces lactis-Aspergillus niger β-galactosidaseDetermination of the pH and temperature optimum. Optimum pH (A) and optimum temperature (B) for the hybrid enzyme between the β-galactosidase of K. lactis and A. niger (red) and the β-galactosidase of K. lactis (blue). Experimental variations are less than10% of the value of the point. Data are the mean of three independent experiments.Back to article page
