Abstract: The invention relates to a process for the hydrolysis of cellulose containing biomass which comprises a 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 by a saccharification step in which a second enzyme composition is added to form oligomeric and/or monomeric sugars; and whereby 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; and whereby the first enzyme or first enzyme composition comprises more endogluconase than the second enzyme composition (expressed in protein wt %).

Abstract translation: 本发明涉及一种水解含纤维素生物质的方法，其包括液化步骤，其中加入第一种酶或第一种酶组合物来液化存在于生物质中的至少部分固体并保持含有纤维素的粘度 生物质在液化步骤中低于1000cP，优选低于800cP，更优选低于600cP; 随后是糖化步骤，其中加入第二种酶组合物以形成低聚和/或单体糖; 并且由此所述第一酶或第一酶组合物不同于所述第二酶组合物; 由此第一酶或第一酶组合物包含内切葡聚糖酶; 由此第二酶组合物包含纤维素酶; 并且由此第一酶或第一酶组合物包含比第二酶组合物更多的内切葡聚糖酶（以蛋白质wt％表示）。
