ABSTRACT:
The invention relates to a process for obtaining a product sugar stream from a cellulosic biomass, comprising pretreating the cellulosic biomass to hydrolyze a portion of the cellulose and hemicellulose to produce glucose, acetic acid and a sugar monomer, adding base to the pretreated cellulosic biomass to produce inorganic salt and acetate salt; hydrolyzing the neutralized cellulosic biomass with cellulase enzymes and separating insoluble residue from the resulting sugar stream; treating the clarified sugar stream using exclusion chromatography at a pH of 5 to 10 to produce a product sugar stream.
