    Abstract: PROBLEM TO BE SOLVED: To provide a method for treating biomass which is capable of markedly improving the yield of monosaccharides.
    SOLUTION: The method for treating biomass includes: the first oligosaccharification step 110 of hydrolyzing hemicellulose in the biomass to obtain an oligosaccharide-containing liquid A1; the first alkali-removing step 130 of removing alkali in the liquid A1; the first monosaccharification step 150 of converting oligosaccharides in the resultant liquid A3 obtained by removing the alkali in the first alkali-removing step 130, into monosaccharides; the second oligosaccharification step 120 of further hydrolyzing residues B1 formed in the step 110 to obtain an oligosaccharide-containing liquid A2; the second alkali-removing step 140 of removing alkali in the liquid A2; and the second monosaccharification step 160 of converting the oligosaccharides in the resultant liquid A4 obtained by removing the alkali in the second alkali-removing step 140, into the monosaccharides.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for saccharifying a biomass, by which a monosaccharide can be obtained in a high yield in a short time.
    SOLUTION: The first pressurizing hot water treatment 110 is performed for a biomass 1. The obtained treatment product is subjected to a solid-liquid separation. The obtained solution is a treated solution A1, and the obtained solid content is a residue B1. The second pressurizing hot water treatment 120 is performed for the residue B1. The obtained treatment product is subjected to a solid-liquid separation. The obtained solution is a treated solution A2, and the obtained solid content is a residue B2. A first catalyst monosaccharification treatment 210 for contacting a solid acid catalyst with the treated solution A1 is performed. The reaction conditions at this time are, for example, a temperature of ≥120 to ≤180°C, a pressure of a saturated steam pressure or higher at the temperature, and a reaction time of ≥30 min to ≤12h. The treated solution A2 is subjected to an enzymatic monosaccharification treatment 220 using an enzyme to obtain the monosaccharide 3.
