Biomass is pretreated using an organic solvent solution under alkaline conditions in the presence of one of more sulfide (hydrosulfide) salt and optionally one or more additional nucleophile to fragment and extract lignin. Pretreated biomass is further hydrolyzed with a saccharification enzyme consortium. Fermentable sugars released by saccharification may be utilized for the production of target chemicals by fermentation.
Une biomasse est prétraitée à l'aide d'une solution de solvant organique dans des conditions alcalines en présence d'un ou plusieurs sels de sulfure (hydrosulfures) et éventuellement d'un ou plusieurs nucléophiles supplémentaires pour fragmenter et extraire de la lignine. La biomasse prétraitée est ensuite hydrolysée par un complexe enzymatique de saccharification. Les sucres fermentables libérés par la saccharification peuvent être employés dans la production de produits chimiques ciblés par fermentation.
