<p>The purpose of the present invention is to provide a sugar-solution production method in which a pre-treated substance of a cellulose-containing biomass and a slurry of an inactivated cellulase are prepared, a filamentous-fungus-derived cellulase is added to the slurry to induce hydrolysis, a hydrolysate is subjected to solid-liquid separation to obtain a solution component and a hydrolysis residue, the solution component is subsequently filtered through an ultrafiltration membrane and the filamentous-fungus-derived cellulase is recovered as a non-filtrate, and a sugar solution is recovered as a filtrate. Accordingly, provided is a method with which, in a cellulose-containing-biomass hydrolysis reaction using a filamentous-fungus-derived cellulase, the reusability of the filamentous-fungus-derived cellulase is improved, and the usage amount of said cellulase is reduced.</p> |
