Abstract
A method of producing a sugar liquid includes hydrolyzing with a filamentous fungus-derived cellulase a product obtained by adding a water-soluble inorganic salt(s) to a pretreated product of cellulose to a final concentration of 5 to 35 g/L; and subjecting the hydrolysate 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.
