Fig. 4From: Purification and characterization of a novel glutamate dehydrogenase from Geotrichum candidum with higher alcohol and amino acid activityEffect of pH (a) and temperature (b) on enzyme activity and stability. In the stability tests, the residual enzyme activity was measured at 30 °C and pH 4.0 after different treatments. In the activity tests, the enzyme activity was measured at 30 °C and different pH values in the pH treatments, and at pH 4.0 and different temperatures in the temperature treatments. The bars in the curves show the standard deviations of the triplicate measurementsBack to article page
