Determination of the thermal stability. Determination of the thermal stability at 30°C (green), 42°C (blue) and 50°C (red) for the hybrid enzyme between the β-galactosidase of K. lactis and A. niger (circles) and the native β-galactosidase of K. lactis (square). Experimental variations are less than 10% of the value of the point. Results are the average of two independent experiments.
