1 The immobilized lactase showed optimal activity at pH 4.5 and 65 degrees C. The immobilized lactase was more heat stable than the free enzyme, and retained 83% of its original activity after 14 d at 55 degrees C. Galactose competitively inhibited the immobilized lactase preparation (Ki 20 m/M). Galactose lactase Homo sapiens
