METHOD FOR ISOLATION AND PURIFICATION OF AMYLASES, AND ADSORBENTS USED FOR THE SAME AS WELL AS DEVICES FOR THE ISOLATION AND PURIFICATION

摘要

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.
