Abstract
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.
