    Abstract: The present invention aims to provide a method of hydrolysis of cellulose using a filamentous fungus-derived cellulase as a carbohydrase, which method comprises the step of adding the carbohydrase to cellulose to perform primary hydrolysis and then subjecting the primary hydrolysate to solid-liquid separation into a primary sugar liquid and solids; the step of adding water to the solids and performing secondary hydrolysis, followed by subjecting the secondary hydrolysate to solid-liquid separation into a secondary sugar liquid and a residue; and the step of filtering the primary sugar liquid and/or secondary sugar liquid through an ultrafiltration membrane, and recovering the carbohydrase from the feed side and recovering a sugar solution from the permeate side. By this, a method to reduce the amount of enzyme, such as cellulase, used in a method for producing a sugar liquid from pretreated cellulose is provided.

    Abstract: [Problem] To provide a filter device capable of stably filtering, at a fixed flow rate, a liquid to be treated. [Solution] This filter device comprises: one or a connected plurality of first units, each comprising a first separation membrane part that separates a liquid to be treated in a first storage tank into a first filtered liquid and a first non-filtered liquid, a first takeout tube that takes out the first non-filtered liquid, a first adjustment unit that keeps the flow rate of the first filtered liquid substantially constant, and a first liquid level meter that detects the liquid level in the first storage tank; a second unit comprising a second separation membrane that separates a storage liquid in a second storage tank in which the first filtered liquid is accumulated into a second filtered liquid and a second non-filtered liquid, a second takeout tube that takes out the second non-filtered liquid, a second adjustment unit that keeps the flow rate of the second filtered liquid substantially constant, and a second liquid level meter that detects the liquid level in the second storage tank; a first control unit that controls the liquid level in the first storage tank on the basis of a measurement value from two connected first units, or a measurement value from a connected first unit and second unit; and a second control unit that controls the liquid level in the second storage tank on the basis of a measurement value from the second unit.

    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.
