Abstract: The present invention improves the filterability in a solid-liquid separation of a saccharified solution using a microfiltration membrane, by adjusting a lignin content of a pretreatment substance derived from a cellulose-containing biomass to 8.5% or lower whereby a cake, in which a solid content in the saccharified solution is concentrated on a membrane surface, is more likely to be formed. In addition, the present invention enables an efficient solid-liquid separation of the saccharified solution using the microfiltration membrane by collecting the cake formed on the membrane surface.

Abstract: To produce a xylooligosaccharide using a xylanase, a xylanase having a low β-xylosidase activity should be used. Under these circumstances, the present invention has been completed on the basis of the finding that, in a process for producing a sugar solution and a xylooligosaccharide in parallel, a xylanase having a low β-xylosidase activity can be prepared at a low cost by recovering a cellulase having been used in a sugar solution production step and reusing the cellulase in a xylooligosaccharide process.
