摘要： 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.

摘要： A novel fungus belongs to the genus Trichoderma whose cellulase can be used to hydrolyze cellulose-based biomass without degradation of xylan contained in the biomass into xylose, and a method produces glucose and xylo-oligosaccharides from a cellulose containing biomass using it. The fungus belonging to the genus Trichoderma includes N- and C-terminal domains of the β-xylosidase 1 (BXL1) gene, but lacks the Fn3-like domain of the gene due to its disruption. The use of this fungus belonging to the genus Trichoderma results in deletion of β-xylosidase activity and increase in β-glucosidase activity. Thus, in hydrolysis of cellulose contained in biomass, xylan contained in the biomass is not degraded into xylose, which enables efficient production of glucose and xylo-oligosaccharides.

摘要： A method of producing a sugar liquid includes steps (1) providing a pretreatment product of a first cellulose-containing biomass; (2) adding a second cellulose-containing biomass or a pretreatment product thereof in an amount ranging from 1 to 50% based on the solid content weight of the first cellulose-containing biomass pretreatment product of step (1), and carrying out hydrolysis by a filamentous fungus-derived cellulase; and (3) subjecting a hydrolysate of step (2) to solid-liquid separation to obtain a solution component and a hydrolysis residue, and filtering the solution component through an ultrafiltration membrane to recover the filamentous fungus-derived cellulase as a retentate and recover a sugar liquid as a permeate.

摘要： A method efficiently produces hydroxycinnamic acids having a high quality, from a cellulose-containing biomass. More specifically, the method includes the steps of: obtaining an alkaline filtrate by allowing an alkaline aqueous medium to pass through a cellulose-containing biomass; obtaining a hydroxycinnamic acid extraction liquid by allowing the alkaline filtrate to repeatedly pass through the cellulose-containing biomass; and separating the hydroxycinnamic acid from the hydroxycinnamic acid extraction liquid.

摘要： A method for selective production of ε-caprolactam, wherein a substance inducible from a biomass resource is used as a material; the reaction process is short; ammonium sulfate is not produced as a by-product; and production of by-products is suppressed; is disclosed. The method for producing ε-caprolactam comprises the step of reacting a particular compound inducible from a biomass resource, such as α-hydromuconic acid, 3-hydroxyadipic acid, or 3-hydroxyadipic acid-3,6-lactone, or a salt thereof with hydrogen or ammonia.
