Abstract
A method for producing saccharides according to the present invention includes a step of preparing a slurry by adding an aqueous solution containing a sugar or a sugar solution to biomass so that the slurry has a biomass content of 10 to 30 w/v %, and a step of adding at least one of an enzyme that degrades cellulose and an enzyme that degrades hemicellulose to the slurry containing the biomass to degrade at least one of cellulose and hemicellulose contained in the biomass, thereby producing saccharides containing glucose as a main component.
Claims4
A method for producing saccharides containing glucose as a main component, the method comprising:
- a) a step of preparing a slurry by adding an aqueous solution containing a sugar or a sugar solution to biomass so that the slurry has a biomass content of 10 to 30 w/v %;
- and
- b) a step of adding at least one of an enzyme that degrades cellulose and an enzyme that degrades hemicellulose to the slurry containing the biomass to degrade at least one of cellulose and hemicellulose contained in the biomass, thereby producing saccharides containing glucose as a main component,
- wherein in the step of preparing the slurry, when a content of the at least one of cellulose and hemicellulose in the slurry is assumed to be X (w/v %), an initial sugar concentration of the slurry is lower than a sugar concentration Y (g/L) represented by relation (1) below,
- Y=−7.7931X+180 (1)
- wherein, in the relation (1), X=W×C/100, where W represents a biomass slurry concentration (w/v %) and C represents a proportion (wt %) of the cellulose and the hemicellulose contained in the biomass.
