Title:
METHOD AND APPARATUS FOR PRODUCING COMPOUND DERIVED FROM LIGNOCELLULOSE-TYPE BIOMASS
Document Type and Number:
WIPO Patent Application WO/2018/074540
Kind Code:
A1
Abstract:
A method for producing a compound derived from a lignocellulose-type biomass comprises: a saccharification step of carrying out a saccharification reaction using a pretreated lignocellulose-type biomass and a saccharification enzyme; a fermentation step of adding a saccharification liquor obtained in the saccharification step, a saccharification residue having the saccharification enzyme adsorbed thereon and microorganisms and then carrying out the fermentation of the resultant solution while stirring; a solid-liquid separation step of, subsequent to the fermentation step, subjecting a fermentation product to solid-liquid separation into a fermentation liquor and a fermentation residue having the saccharification enzyme adsorbed thereon; a stirring step of adding water to the fermentation residue having the saccharification enzyme adsorbed thereon, which is the residue obtained in the solid-liquid separation step, and then stirring the resultant solution while keeping the temperature of the solution at a temperature at which the saccharification enzyme can cause a saccharification reaction; and a recycling step of recycling a fermentation residue solution produced in the stirring step to the saccharification step.
