METHOD FOR ENZYMATIC SACCHARIFICATION TREATMENT OF LIGNOCELLULOSE-CONTAINING BIOMASS, AND METHOD FOR PRODUCING ETHANOL FROM LIGNOCELLULOSE-CONTAINING BIOMASS

摘要

Provided is a method for the enzymatic saccharification treatment of alignocellulose-based raw material, in which a lignocellulose-based rawmaterial whichhas been subjected to a pretreatment for making the raw material appropriatefor anenzymatic saccharification reaction, is added together with an electrolytecontaining awater-soluble salt, to cellulose saccharification enzyme-containing water; thelignocellulose-based raw material as a raw material suspension whoseelectricalconductivity has been adjusted to 5 mS/cm to 25 mS/cm, is subjected to anenzymaticsaccharification treatment through an enzymatic saccharification reaction; thereactionproduct and an enzyme-containing solution are separated and recovered from thetreatedsuspension after the enzymatic saccharification treatment; and the recoveredenzyme-containing solution is recycled as an enzyme for the enzymaticsaccharificationtreatment process.
