Abstract

La présente invention concerne un traitement de pâte de cellulose à dissoudre à l'aide d'une monooxygénase polysaccharidique lytique. Le traitement par la monooxygénase polysaccharidique lytique a pour conséquence une viscosité réduite et/ou une régulation de viscosité améliorée dans le processus de production de pâte de cellulose à dissoudre et/ou une réactivité accrue de la pâte de cellulose à dissoudre.
