Abstract: Cellulose from lignocellulosic biomass which also contains protein, such as grasses and straws, can be enzymatically converted to valuable products such as glucose at lower enzyme consumption by: (a) extracting the biomass with water at 15-75 °C to produce an extracted biomass and a protein-containing aqueous extract; (b) mechanically, chemically and/or thermally pretreating cellulose-containing-biomass, in particular by organosolv treatment; and (c) contacting biomass pretreated in step (b) with: (i) an enzyme capable of hydrolysing cellulose; and (ii) the protein-containing aqueous extract obtained in step (a).

Abstract: The present invention is directed at a process for fractionating lignocellulosic biomass for the purpose of reducing processing costs, increasing delignification, reducing side-reactions, in particular reducing hemicelluloses degradation, improving cellulose hydrolysis and increasing the nativity of the obtained lignin, by performing organosolv fractionation of the biomass with a treatment liquid at a temperature below 170° C., wherein the treatment liquid comprises a non-hydroxylic organic solvent, in particular a ketone, water and some acid, and optionally subjecting the cellulose-enriched product stream to enzymatic hydrolysis.
