    Abstract: A method for producing a sugar solution, which comprises steps (1) to (3) mentioned below. The method enables the utilization of a hydrothermal treatment solution of a cellulose-containing biomass, which has been treated as a liquid waste, for the production of a sugar solution. Step (1): subjecting a cellulose-containing biomass to a hydrothermal treatment and then separating the resultant solution into a hydrothermal treatment solution and a cellulose-containing solid material. Step (2): adding a filamentous fungus-originated cellulase to the cellulose-containing solid material produced in step (1) to cause cellulose to be hydrolyzed, and then separating the resultant solution into a glycosylation residue and the sugar solution. Step (3): washing the glycosylation residue produced in step (2) with the hydrothermal treatment solution obtained in step (1) to cause the filamentous fungus-originated cellulase, onto which the glycosylation residue has been adsorbed, to be eluted in the hydrothermal treatment solution, and then subjecting the resultant solution to solid/liquid separation to produce a solution component containing the filamentous fungus-originated cellulase.

    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.

    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).
