Title (EN) OXIDATIVE TREATMENT OF BIOMASS TO ENHANCE ENZYMATIC SACCHARIFICATION
(FR) TRAITEMENT OXYDANT DE LA BIOMASSE POUR AUGMENTER LA SACCHARIFICATION ENZYMATIQUE
Abstract:
(EN) Lignocellulosic biomass comprising lignin is treated by selective extraction and oxidation of lignin using a solvent solution comprising water in combination with at least one Mn(III) salt to produce readily saccharifiable carbohydrate enriched biomass.
(FR) Selon l'invention, une biomasse lignocellulosique comprenant de la lignine est traitée par extraction sélective et oxydation de lignine à l'aide d'une solution dans un solvant comprenant de l'eau en combinaison avec au moins un sel de Mn(III) pour produire de la biomasse enrichie en glucides facilement saccharifiable.
