    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 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 of producing a sugar liquid from cellulose-containing biomass includes (1) to (4): (1) subjecting a cellulose-containing biomass to a dilute sulfuric acid treatment and thereafter separating the treated cellulose-containing biomass into a dilute sulfuric acid-treated liquid and a cellulose-containing solid content; (2) adding a cellulase to the cellulose-containing solid content to hydrolyze the cellulose and thereafter obtaining a sugar liquid; (3) filtering the dilute sulfuric acid-treated liquid through a nanofiltration membrane at pH 2.5 or lower to thereby separate a sugar concentrated liquid as a retentate and at the same time recover a sulfuric acid aqueous solution as a permeate; and (4) reusing the whole amount or a part of the sulfuric acid aqueous solution obtained in (3) in the dilute sulfuric acid treatment in (1).

    摘要： A method of producing cellulase includes steps (1) to (3): (1) subjecting an aqueous solution of cellulase derived from filamentaous fungi to filtration through an ultrafiltration membrane with a molecular weight cut off of 100,000 to 200,000 to obtain a filtrate and concurrently obtain a concentrated enzyme liquid as a retentate; (2) further subjecting the filtrate obtained in step (1) to filtration through a second ultrafiltration membrane with a molecular weight cut off of 5,000 to 50,000 to obtain a second concentrated enzyme liquid as a retentate; and (3) mixing the concentrated enzyme liquid obtained in steps (1) and (2) to obtain cellulase derived from filamentaous fungi.
