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.

A method of producing xylo-oligosaccharides comprising hydrolyzing a biomass containing xylan and cellulose with a cellulase composition,
- wherein said cellulase composition has at least activities of xylanase, cellobiohydrolase and β-glucosidase and is substantially free of β-xylosidase activity against said biomass during hydrolysis, and said cellulase composition comprises enzymatic active components obtained by substantial inactivation of activities of β-glucosidase and β-xylosidase against said biomass by incubation of a cellulase mixture originated from a fungus belonging to the genus Trichoderma having at least activities of xylanase, cellobiohydrolase, β-glucosidase and β-xylosidase against said biomass.
