METHOD FOR ENZYMATIC SACCHARIFICATION OF LIGNOCELLULOSIC BIOMASS, AND METHOD FOR MANUFACTURING ETHANOL FROM LIGNOCELLULOSIC BIOMASS

摘要

A method for the enzymatic saccharification of a lignocellulosic raw material, characterized in: adding a pretreated lignocellulosic raw material as a material suitable for an enzymatic saccharification reaction, together with an electrolyte composed of a water-soluble salt, to water that contains a cellulose saccharification enzyme; saccharifying the raw material by an enzymatic saccharification reaction, as a suspension of the raw material having an electrical conductivity adjusted to 5-25 mS/cm and; separating and recovering a reaction product and an enzyme-containing solution from the enzymatically saccharified treatment suspension; and recycling the recovered enzyme-containing solution as the enzyme for the enzymatic saccharification step.
