Patent attributes
The invention relates to a process for the hydrolysis of cellulose containing biomass which comprisesa liquefaction step in which a first enzyme or first enzyme composition is added to liquefy at least part of the solids present in the biomass and to keep the viscosity of the cellulose containing biomass below 1000 cP, preferably below 800 cP, more preferably below 600 cP in the liquefaction step; followed bya saccharification step in which a second enzyme composition is added to form oligomeric and/or monomeric sugars; andwhereby the first enzyme or first enzyme composition is different from the second enzyme composition;whereby the first enzyme or first enzyme composition comprises an endoglucanase;whereby the second enzyme composition comprises a cellulase; andwhereby the first enzyme or first enzyme composition comprises more endogluconase than the second enzyme composition (expressed in protein wt %).
