Abstract: The present invention aims to produce a sugar liquid hardly containing fermentation inhibitors. The present invention is a method for concentrating an aqueous cellulose-derived sugar solution with a nanofiltration membrane and/or reverse osmosis membrane, wherein a sugar liquid is produced by adding an anionic polymer to remove fermentation inhibitors into the permeate side of the nanofiltration membrane and/or reverse osmosis membrane.

Abstract: In a process of producing a sugar liquid from a woody biomass, the conventional techniques have such a problem that a specific component contained in the sugar liquid from the woody biomass remarkably deteriorates the filtration performance when the sugar liquid is filtrated through a microfiltration membrane and/or an ultrafiltration membrane. In the present invention, it becomes possible to improve the filtration performance of the sugar liquid through the microfiltration membrane and/or the ultrafiltration membrane, and it also becomes possible to produce the sugar liquid with high efficiency by hydrolyzing the woody biomass to produce a liquid component and then reacting the liquid component with a mannanase.

Abstract: The present invention relates to a method of efficiently producing hydroxycinnamic acids having a high quality, from a cellulose-containing biomass. More specifically, the present invention relates to a method of producing hydroxycinnamic acids, the method including the steps of: obtaining an alkaline filtrate by allowing an alkaline aqueous medium to pass through a cellulose-containing biomass; obtaining a hydroxycinnamic acid extraction liquid by allowing the alkaline filtrate to repeatedly pass through the cellulose-containing biomass; and separating the hydroxycinnamic acid from the hydroxycinnamic acid from the hydroxycinnamic acid extraction liquid.

Abstract: In a method for producing a sugar liquid comprising filtering a sugar liquid through a nanofiltration membrane and collecting a sugar liquid from the feed side, loss of sugar into the permeate side of the nanofiltration membrane can be reduced by filtering a sugar liquid containing an organic liquid compound having a relative dielectric constant of not less than 17 at 25?C through the nanofiltration membrane.

Abstract: By filtering an aqueous sugar solution obtained by hydrolysis of a cellulose-containing biomass through an ultrafiltration membrane having a molecular weight cutoff of 600 to 2,000 to remove fermentation inhibitors into the permeate side and collect a sugar liquid from the feed side, a sugar liquid containing only a very small amount of fermentation inhibitors can be produced.

Abstract: A method for producing a sugar liquid by processing a cellulose-derived sugar liquid through one or more of separation membranes selected from ultrafiltration membranes, nanofiltration membranes and reverse osmosis membranes, wherein a separation membrane (s) contaminated due to the filtration is/are washed with warm water at a temperature of not less than 50oC to achieve effective washing of the contaminated separation membranes (s).
