Abstract:
Concentrated sugar solutions obtained from polysaccharide enriched biomass by contacting biomass with water and at least one nucleophilic base to produce a polysaccharide enriched biomass comprising a solid fraction and a liquid fraction and then contacting enriched biomass with a dilute mineral acid selected from the group consisting of sulfuric acid, phosphoric acid, hydrochloric acid, nitric acid, or a combination thereof, to produce an intermediate saccharification product, which is contacted with an enzyme consortium to produce a final saccharification product comprising fermentable sugars.
