Abstract: A method for producing a sugar solution by treating a cellulose-containing biomass with dilute sulfuric acid, said method comprising the below-mentioned steps (1) to (4). In the method, a higher treatment effect can be achieved compared with those achieved in the conventional treatment methods with dilute sulfuric acid. Step (1): a step of treating the cellulose-containing biomass with dilute sulfuric acid and then separating the resultant solution into a dilute sulfuric acid-treated solution and a cellulose-containing solid material. Step (2): a step of adding a cellulase to the cellulose-containing solid material to hydrolyze the cellulose-containing solid material, thereby producing a sugar solution. Step (3): a step of filtrating the dilute sulfuric acid-treated solution through a nano-filtration membrane at a pH of 2.5 or lower to separate out a sugar-rich solution as a non-filtrate and collect an aqueous sulfuric acid solution as a filtrate. Step (4): a step of reusing the whole or a portion of the aqueous sulfuric acid solution obtained in step (3) in the treatment with dilute sulfuric acid in step (1).

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: A method for manufacturing a sugar solution by repeating a sugar solution manufacturing process comprising steps (1) - (3) below, said manufacturing process being characterised by the use of a recovered saccharifying enzyme obtained during step (3) in step (1) of subsequent sugar solution manufacturing processes. Step (1): cellulose undergoes primary hydrolysis by adding a cellulase from a filamentous fungus thereto. Step (2): unused cellulase from the filamentous fungus is added to the hydrolysis product from step (1) and a secondary hydrolysis is carried out. Step (3): the hydrolysis product from step (2) undergoes solid-liquid separation, and a recovered enzyme is obtained from the acquired sugar solution. 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.
