Abstract
A method produces xylo-oligosaccharides from a biomass containing xylan and cellulose, which method is convenient and has a high yield of xylo-oligosaccharides because of inhibition of degradation of xylo-oligosaccharides into xylose. In the method of producing xylo-oligosaccharides, a biomass containing xylan and cellulose is hydrolyzed with a cellulase composition having at least activities of xylanase, cellobiohydrolase and β-glucosidase and substantially free of β-xylosidase activity during hydrolysis.
