Final Purification

Inulinase was produced from local isolate of Aspergillus niger J3. The inulinase was purified by two steps included precipitation by amonium sulphate at (30-80) % sa-turation and gel filtration on sephadex G100. The final purification folds and the yield of the enzyme were 3.15 times and 28.24%, respectively. The purified enzyme has the following characteristics: The optimum pH of the enzyme activity was 5.5. The enzyme was most stable at pH (4.5 - 6). The optimum temperature for its activity was 45c. The enzyme retained its original activity when incubates at (30-55) c for 20 minutes. Mercury chloride inhibited the enzyme completely at concentration of 10mM, cupper sulphate and calisium chloride inhibited the enzyme at concentrations of 85% and 7% respectively. It was revealed that the enzyme had the efficiency to hydrolyze 87% of 5% inulin solution when treated at 45c for 120 min.
