Abstract:
(EN) The present invention generally relates to the field of celluloses, in particular nanocelluloses, and more particularly to methods for producing cellulosic fibres and defibrillating cellulosic substrates. In particular, the invention relates to methods for defibrillating cellulosic substrates and producing celluloses, in particular nanocelluloses (NC), using a new family of fungal lytic polysaccharide monooxygenases (LPMO).
(FR) La présente invention concerne de manière générale le domaine des celluloses, notamment de nanocelluloses, et plus particulièrement des procédés pour la fabrication de fibres de celluloses et de défïbrillation de substrats cellulosiques. Tout particulièrement, l'invention concerne des procédés de défïbrillation de substrats cellulosiques et de fabrication de celluloses, en particulier de nanocelluloses (NC), utilisant une nouvelle famille de Lytic polysaccharide monooxygenases (LPMO) fongiques.
