Immobilization of invertase on rice husk using polyethylenimine.
Washed and dried rice husk was coated with 2% polyethylenimine (PEI). Invertase was immobilized on this support through adsorption followed by cross-linking with 2% glutaraldehyde. Immobilized enzyme was reused for the hydrolysis of sucrose without loss in activity. This approach may serve as a simple technique in the future for the covalent immobilization of enzymes on lignocellulosic supports.
