| description | The present disclosure relates to a process for extracting sugars from a pretreated lignocellulosic biomass. This process consists of contacting the pretreated lignocellulosic biomass with low charges of an aqueous peroxy acid (PA) solution to produce a liquid fraction (containing a small amount of lignin and hemicellulose degradation products) and a solid fraction containing cellulose, hemicellulose and lignin. The solid fraction can then be subjected to enzymatic hydrolysis with a variety of cell wall-degrading enzymes to produce a lignin-rich residue and a sugar solution that can be fermented to a variety of (bio)chemicals.
La présente invention concerne un procédé d'extraction de sucres à partir d'une biomasse lignocellulosique prétraitée. Ce procédé consiste à mettre en contact la biomasse lignocellulosique prétraitée avec des charges faibles d'une solution aqueuse de peroxyacide (PA) pour produire une fraction liquide (contenant une petite quantité de produits de dégradation de la lignine et l'hémicellulose) et une fraction solide contenant de la cellulose, de l'hémicellulose et de la lignine. La fraction solide peut ensuite être soumise à hydrolyse enzymatique avec une variété d'enzymes dégradant la paroi cellulaire pour produire un résidu riche en lignine et une solution de sucre qui peut être fermentée pour obtenir une variété de substances (bio)chimiques. |
