Abstract
Biomass is pretreated using an organic solvent solution under alkaline conditions in the presence of elemental sulfur and optionally one or more alkylamine and/or 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.
