Abstract

La présente invention concerne des procédés et une composition permettant de réguler la catalase par traitement ou par mise en contact d'un système contaminé par catalase avec une protéase. Ce traitement par protéase peut être utilisé pour améliorer des opérations de traitement au peroxyde, telles que des opérations de blanchiment au peroxyde, dont la réalisation est compromise par l'activité catalase résultant d'une croissance microbienne dans le système. La présente invention concerne également des procédés et une composition permettant de réguler la catalase dans la fabrication de la pâte et du papier.
