Abstract

La présente invention est relative à une nouvelle maltase et à son procédé de préparation. La nouvelle maltase est préparée en cultivant une souche de Saccharomyces (déposée à l'ATCC sous le n degrés 20.488), dans un milieu de culture contenant au moins l'une des substances prises dans le groupe du maltose, du maltotriose ou d'un extrait de malt provenant d'une source végétale, en libérant l'enzyme des cellules de levure, et en la récuperant. Application pour le dosage d'amylases.
