ABSTRACT:
Insolubilized but active enzymes are prepared by mixing an aqueous solution of the enzyme with an aqueous solution of chitosan and then adding a polyfunctional cross-linking agent to form a gel. The so-produced gel is reacted with a reducing agent to form a granular insolubilized enzyme, which has retained a substantial part of its original activity.
