Title (EN) METHOD FOR PREPARING FERMENTABLE SUGARS FROM LIGNOCELLULOSIC BIOMASS
(FR) PROCÉDÉ DE PRÉPARATION DE SUCRES FERMENTESCIBLES À PARTIR DE BIOMASSE LIGNOCELLULOSIQUE
Abstract:
(EN) A method for providing a C5/C6 product from a lignocellulosic material is disclosed, said method comprising the steps: (i) pretreatment of the lignocellulosic material; (ii) solid/liquid separation of the pretreated lignocellulosic material from step (a) into a first solid fraction and a first liquid fraction; (iii) enzymatic fiber hydrolysis of said first solid fraction from step (b) by use of an enzyme composition capable of degrading lignocellulosic material, thereby providing a C5/C6 fiber slurry comprising C5 and/or C6 sugars; (iv) solid/liquid separation of the C5/C6 fiber slurry from step (c) into a second solid fraction and a second liquid fraction; and optionally (v) combining said first liquid fraction and said second liquid fraction for enzymatic mixed sugar hydrolysis (MSH), whereby a MSH C5/C6 product is provided.
(FR) L'invention concerne un procédé de fourniture d'un produit en C5/C6 à partir d'un matériau lignocellulosique, ledit procédé comprenant les étapes suivantes : (i) prétraitement du matériau lignocellulosique; (ii) séparation solide/liquide du matériau lignocellulosique prétraité de l'étape (a) en une première fraction solide et en une première fraction liquide; (iii) hydrolyse enzymatique des fibres de ladite première fraction solide de l'étape (b) au moyen d'une composition enzymatique capable de dégrader le matériau lignocellulosique, fournissant ainsi une suspension de fibres en C5/C6 comprenant des sucres en C5 et/ou en C6; (iv) séparation solide/liquide de la suspension de fibres en C5/C6 de l'étape (c) en une seconde fraction solide et en une seconde fraction liquide; et, éventuellement, (v) combinaison de ladite première fraction liquide et de ladite seconde fraction liquide pour une hydrolyse enzymatique des sucres mélangés (MSH), donnant un produit de MSH en C5/C6.
