Abstract
Nouveaux procédés favorisant l'expression et la sécrétion de lactase à partir de champignons filamenteux. Spécifiquement, lesdits nouveaux procédé permettent d'accroître la production de lactase à partir d'un Aspergillus et de préférence d'accroître la production de lactase tirée de A. oryzae à partir de souches hôtes de A. oryzae transformées à l'aide de l'ADN nécessaire. Une séquence d'ADN codant le gène de lactase de A. oryzae et la séquence déduite d'acides aminés de la lactase provenant de A. oryzae sont également décrites.
