- •
Immobilized GI supported by silica/chitosan hybrid microspheres was prepared in an easy approach through in situ encapsulation of GI in the support.
- •
The conversion of glucose to fructose could finish in 10 min catalyzed by immobilized GI due to reduced mass transfer resistance.
- •
The immobilized GI had much wider stability ranges of pH, temperature, ions, storage and operation in comparison with free GI.
