Abstract
A method produces a sugar liquid by adding a filamentous fungus-derived cellulase to a pretreated product of cellulose to obtain a hydrolysate; adding waste molasses to said hydrolysate to obtain a mixed sugar liquid; and subjecting said mixed sugar liquid to solid-liquid separation and filtering the obtained solution component through an ultrafiltration membrane, to recover the filamentous fungus-derived cellulase as a non-permeate and to obtain a sugar liquid as a permeate.
