Degradation of commercially available immobilized Glucose Isomerase enzyme was studied in a batch reactor. Effect of shearing on the degradation was studied by comparing the performance of a basket type reactor ( with enzyme kept inside the stirrer) and ordinary batch reactor ( with enzyme kept outside the stirrer).

Invertase enzyme is available commercially in a free soluble form. It was coupled with a new kind of starch derivative. The coupling efficiency achieved was 8.7 % and the concentration of the immobilized enzyme was 718 U invertase per gram of starch. The deactivation of enzyme-starch gel was studied in a batch reactor.
