Advantage of Immobilization - 1. Enzymes are costly items. Immobilization permits their repeated use.

2. The product is readily freed from the enzyme.

3. Immobilized enzymes can be used in nonaqueous systems as well.

4. Continuous production systems can be used, which is not possible with free enzymes.

5. Thermostability of some enzymes may be increased.

6. Recovery of enzyme may also reduce effluent handling problems.

7. Enzymes can be used at much higher concentrations than free enzyme.
