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: 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.
