Abstract: In order to address the problem of establishing a method for recovering coumaramide obtained by treating cellulosic biomass using an ammonia-containing treatment agent, this method for producing coumaramide is characterized by including: a pre-treatment step for obtaining ammonia-treated biomass by treating cellulosic biomass using an ammonia-containing treatment agent; an extraction step for immersing the ammonia-treated biomass into a solvent containing at least water, and obtaining a coumaramide solution by eluting the coumaramide present in the ammonia-treated biomass in the solvent; and a crystallization step for obtaining a coumaramide crystal by precipitating the coumaramide in the coumaramide solution as a crystal.

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: The present invention aims to provide a method for producing a sugar liquid by repeating a sugar liquid production process comprising the Steps (1) to (3) below: (1) the step of adding a filamentous fungus-derived cellulase to cellulose to perform primary hydrolysis; (2) the step of adding a fresh filamentous fungus-derived cellulase to the hydrolysate in Step (1) to perform secondary hydrolysis; and (3) the step of subjecting the hydrolysate in Step (2) to solid-liquid separation to obtain a sugar liquid, from which a recovered enzyme is obtained; wherein the recovered enzyme obtained in Step (3) is used for Step (1) of the next and later sugar liquid production processes. By this, the present invention provides a method for reducing the amount of enzyme used, such as cellulase, in a method for producing a sugar liquid from pretreated cellulose.

Abstract: Provided is a method for producing a sugar liquid using a cellulose-containing biomass as the starting material. Sugar liquid having a very low fermentation-inhibiting substance content is produced by a method comprising (1) a step in which a cellulose-containing biomass is hydrolyzed to produce an aqueous sugar solution and (2) a step in which the resulting aqueous sugar solution is filtered through a nanofiltration membrane and/or reverse osmosis membrane, the pure sugar liquid is recovered from the unpermeated side, and the fermentation-inhibiting matter is removed from the permeated side.

Abstract: A method for producing a sugar solution, which comprises steps (1) to (3) mentioned below. The method enables the utilization of a hydrothermal treatment solution of a cellulose-containing biomass, which has been treated as a liquid waste, for the production of a sugar solution. Step (1): subjecting a cellulose-containing biomass to a hydrothermal treatment and then separating the resultant solution into a hydrothermal treatment solution and a cellulose-containing solid material. Step (2): adding a filamentous fungus-originated cellulase to the cellulose-containing solid material produced in step (1) to cause cellulose to be hydrolyzed, and then separating the resultant solution into a glycosylation residue and the sugar solution. Step (3): washing the glycosylation residue produced in step (2) with the hydrothermal treatment solution obtained in step (1) to cause the filamentous fungus-originated cellulase, onto which the glycosylation residue has been adsorbed, to be eluted in the hydrothermal treatment solution, and then subjecting the resultant solution to solid/liquid separation to produce a solution component containing the filamentous fungus-originated cellulase.

Abstract: A method for producing a sugar solution, which comprises the steps of filtrating a sugar solution by allowing the sugar solution to pass through a nano-filtration membrane and then collecting the sugar solution from the non-permeation side of the membrane, wherein a sugar solution containing an organic liquid compound having a relative permittivity of 17 or more at 25˚C is filtrated by allowing the sugar solution to pass through the nano-filtration membrane. In this manner, the loss of a sugar toward the permeation side of the nano-filtration membrane can be reduced.
