Abstract
A method produces a sugar liquid by repeating a sugar liquid production process including (1) to (3): (1) adding a filamentous fungus-derived cellulase to cellulose to perform primary hydrolysis; (2) adding a fresh filamentous fungus-derived cellulase to the hydrolysate in Step (1) to perform secondary hydrolysis; and (3) subjecting the hydrolysate in Step (2) to solid-liquid separation to obtain a sugar liquid, from which a recovered enzyme is obtained; wherein the recovered enzyme obtained in Step (3) is used for Step (1) of the next and later sugar liquid production processes.
