Treatment of Biomass to Obtain Fermentable Sugars

NREL (Inventor)

Research output: Patent


Biomass is pretreated using a low concentration of aqueous ammonia at high biomass concentration. 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.
