Abstract

Enzymes are immobilized on a solid support material containing essentially cellulose and lignin by a process involving oxidation of the support to provide aldehyde groups, amination of the oxidized support by reacting a diamine with the aldehyde groups, reduction of the aminated support to produce stabilized aminated groups, activation of the aminated groups by reacting the groups with a dialdehyde and immobilization of an enzyme by covalent coupling of the enzyme to the activated groups of the support. The enzyme may be invertase and the immobilized invertase can be used to treat a sugar syrup.
