Abstract: A method for producing a sugar solution by processing a cellulose-derived sugar solution with use of one or more separation membranes selected from among an ultrafiltration membrane, a nanofiltration membrane and a reverse osmosis membrane. In this method for producing a sugar solution, a separation membrane that has been contaminated through filtration can be effectively cleaned by cleaning the contaminated separation membrane with hot water at 50˚C or more.

Abstract: A method for cellulolysis which uses a cellulase from a filamentous fungus as a saccharifying enzyme, and in which: cellulose undergoes primary hydrolysis by adding a saccharifying enzyme thereto, after which the primary hydrolysis product is separated into a primary sugar solution and solid material by solid-liquid separation; water is added to the solid material, and a secondary hydrolysis is carried out, after which the secondary hydrolysis product is separated into a secondary sugar solution and residue by solid-liquid separation; and the primary sugar solution and/or the secondary sugar solution is/are passed through an ultrafiltration membrane, after which the saccharifying enzyme is collected from the film side and the sugar solution is collected from the permeating side. Thus provided is a method for reducing the amount of an enzyme such as cellulase used in a method for manufacturing a sugar solution from a pretreated cellulose material.

Abstract: The present invention relates to a method for producing a high-quality sugar liquor from a cellulose-containing biomass with high efficiency. More specifically, the present invention relates to a method for producing a sugar liquor, said method comprising: a step of causing an alkaline aqueous medium to pass through a cellulose-containing biomass to produce an alkaline filtrate; a circulation filtration step of causing the alkaline filtrate to pass through the cellulose-containing biomass repeatedly to produce a cellulose-containing solid material; and a step of hydrolyzing the cellulose-containing solid material to produce the sugar liquor.

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.
