ABSTRACT:
Cross-linked polyglucans obtained by cross-linking polyglucans having branched chains intermolecularly and/or intramolecularly or cross-linked homooligomers obtained by cross-linking .alpha.-1,4-linked homooligomers of glucose intermolecularly can selectively adsorb glucoamylase and/or .beta.-amylase thereto. By the use of such three-dimensional, cross-linked high molecular weight substances, glucoamylase and .beta.-amylase can be isolated and purified extremely efficiently.
