a Activity versus pH profiles of the partially purified β-galactosidase. Enzyme activity is plotted as a % value relative to the activity displayed at the enzyme’s optimum pH. Error bars indicate the standard deviation of the measured data values from the mean, n = 3. b Activity versus temperature profiles of the partially purified β-galactosidase. Enzyme activity is plotted as a % value relative to the activity displayed at the enzyme’s optimum temperature. Error bars indicate the standard deviation of the measured data values from the mean, n = 3. c Temperature stability of the β-galactosidase partially purified from A. niger at 4 °C, 50 °C and 70 °C
