Abstract: The present invention relates to a method for efficiently producing high-quality hydroxycinnamic acids from a cellulose-containing biomass. More specifically, the present invention relates to a method for producing hydroxycinnamic acids, which comprises: a step for obtaining an alkaline filtrate by causing an alkaline aqueous medium to permeate through a cellulose-containing biomass; a step for obtaining an extract solution of hydroxycinnamic acids by repeatedly causing the alkaline filtrate to permeate through the cellulose-containing biomass; and a step for separating the hydroxycinnamic acids from the extract solution of the hydroxycinnamic acids.

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: A method for producing a sugar solution by filtering a cellulose-derived sugar solution through one or more separation membranes selected from an ultrafiltration membrane, a nanofiltration membrane, and a reverse-osmosis membrane, wherein separation membranes which are dirty as a result of the filtration are cleaned using a cleaning fluid containing an acidic substance and an aromatic compound. As a result, it is possible to effectively clean dirty separation membranes.

Abstract: The present invention improves the filterability in a solid-liquid separation of a saccharified solution using a microfiltration membrane, by adjusting a lignin content of a pretreatment substance derived from a cellulose-containing biomass to 8.5% or lower whereby a cake, in which a solid content in the saccharified solution is concentrated on a membrane surface, is more likely to be formed. In addition, the present invention enables an efficient solid-liquid separation of the saccharified solution using the microfiltration membrane by collecting the cake formed on the membrane surface.
