Zusammenfassung:Provided is a method for the enzymatic saccharification treatment of a lignocellulose-based raw material, in which a lignocellulose-based raw material which has been subjected to a pretreatment for making the raw material appropriate for an enzymatic saccharification reaction, is added together with an electrolyte containing a water-soluble salt, to cellulose saccharification enzyme-containing water; the lignocellulose-based raw material as a raw material suspension whose electrical conductivity has been adjusted to 5 mS/cm to 25 mS/cm, is subjected to an enzymatic saccharification treatment through an enzymatic saccharification reaction; the reaction product and an enzyme-containing solution are separated and recovered from the treated suspension after the enzymatic saccharification treatment; and the recovered enzyme-containing solution is recycled as an enzyme for the enzymatic saccharification treatment process.
