Abstract: Disclosed is a cellulose-based filter aid with high turbidity removal capability, and a manufacturing method thereof. This method of manufacturing a filter aid involves (A) grinding and/or thermochemically treating a cellulose-containing biomass to obtain a pre-treated biomass, (B) a step for treating with cellulase the pre-treated biomass obtained in step (A) to obtain a cellulase-treated product, and a step (C) for obtaining the solid component of the cellulase-treated product of step (B). This cellulose-based filter aid contains the water-insoluble cellulase-treated product of a cellulose-containing biomass.

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: 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.

Abstract: Provided is a method for removing, during a step for producing a sugar solution, a fermentation inhibiting substance, which is generated during a step for producing sugar from a cellulose-containing biomass. Also provided is a method for steadily generating a pure sugar solution, which has an extremely low content of a fermentation inhibiting substance, over a long period of time. Specifically, disclosed is a method for producing a pure sugar solution, which uses a cellulose-containing biomass as the starting material and which involves: a step (1) for producing a sugar solution by subjecting a cellulose-containing biomass to decomposition treatment; a step (2) for subjecting the sugar solution obtained in step (1) to coagulation treatment; a step (3) for filtering the sugar solution obtained in step (2) by means of a microfiltration membrane and/or an ultra-filtration membrane, and for collecting the sugar solution from the permeate side; and a step (4) for filtering the sugar solution obtained in step (3) by means of a nano-filtration membrane and/or a reverse osmosis membrane, for collecting the pure sugar solution from the non-permeate side, and for removing a fermentation inhibiting substance from the permeate side.

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.
