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: Method for producing sugar liquidAbstractA sugar liquid containing only very small amounts of fermentation-inhibiting substances is produced by a method for producing a sugar liquid using a cellulose containing biomass as a raw material, the method comprising: (I) a step of hydrolyzing a cellulose-containing biomass to produce an aqueous sugar solution; and (2) a step of filtering the obtained aqueous sugar solution through a nanofiltration membrane and/or reverse osmosis membrane to collect a purifiedsugar liquid from the feed side, while removing fermentation-inhibiting substances from the permeate side.

Abstract: A fluorine resin polymer separation membrane and a manufacturing method of the same, which are excellent in a virus-eliminating property, further excellent in water permeability, chemical strength (chemical resistance), physical strength, and an antifouling property, and particularly suitable for practicable use as a filtration membrane for the elimination of viruses, are provided. A fluorine resin polymer separation membrane includes a layer having a three-dimensional network structure and a layer having a spherical structure, in which the layer having a three-dimensional network structure does not substantially contain micro-voids having a void diameter of 5 µm or more, and the fluorine resin polymer separation membrane has filtration performance represented by the elimination rate of 80% or more of dextran having molecular weight of 75,000. The layer having a three-dimensional network structure is formed by the solidification with a polymer solution containing a fluorine resin polymer and cellulose ester.

Abstract: With porous membranes in the related art, if the porous membrane is used with a filtration undiluted solution that is easily contaminated, membrane closure occurred due to turbidity separated by filtration and, as a result, membrane clogging occurred, and permeation performance readily deteriorated. The purpose of the present invention is to provide a porous membrane that has high permeability and excellent stain resistance, and is capable of maintaining high filtrate permeability with respect to a filtration undiluted solution that is easily contaminated. A porous membrane according to the present invention comprises polyvinylidene fluoride resin, and, given surface A as one surface thereof and surface B as the other surface thereof, has a ratio (H
