The invention relates to processes of closing an observed gap in sugar yield between pure batch hydrolysis and a multi-stage hydrolysis containing a continuous reactor. Enzyme compositions containing varied ratios of cellulolytic composition and a hemicellulolytic composition preconditioning are used in multi-stage hydrolysis processes containing a continuous reactor in order to close the gap. Such enzyme compositions are useful in multi-stage saccharification of a lignocellulosic material, fermentation processes following multi-stage saccharification of a lignocellulosic material and in improving a glucose or xylose yield in multi-stage saccharification of a lignocellulosic material.
