Abstract
L'invention concerne un procédé de préparation d'acylases fixées sur un support. Selon l'invention, on fait réagir une acylase soluble avec des groupes réactifs fixés chimiquement de dérivés de cellulose obtenus par fonctionnalisation de la cellulose dans des solutions de cette dernière dans du diméthylsulfoxyde contenant du polyoxyméthylène. Application Produits d'immobilisation d'acylases.
