Abstract

Résines échangeuses d'ions porteuses de gluco-amylase. La résine utilisée est un polymère de styrène réticulé avec du divinyl-benzène de type microréticulé. Le procédé pour l'obtention de ces résines consiste à sécher la résine sous vide et à la mettre en contact avec une solution de glucoamylase dans un tampon pendant 6 à 24 heures, à une température de 1 à 10 degrés C. Application : hydrolyse du maltose, de dextrines et d'amidon.
