Effect of the temperature on the stability of the free and immobilized ARG I. a Immobilized enzyme was incubated at 40, 50 and 60 °C for 0–220 min; b Free enzyme was incubated under the same conditions as the immobilized enzyme; The residual activity was determined at 40 °C, pH 10. In both figure (a) and (b) the activity of the enzyme at 0 min was taken as 100 %
