METHOD FOR REMOVING FERMENTATION INHIBITORY MATERIAL IN HYDROLYSATE

摘要

PROBLEM TO BE SOLVED: To provide a method for removing a fermentation inhibitory material contained in a treated material without reducing the yield of sugars in hydrolyzing a polysaccharide biomass and subjecting the obtained hydrolysate to ethanol fermentation.

SOLUTION: This method for removing the fermentation inhibitory material in hydrolyzing the polysaccharide biomass and subjecting the obtained hydrolysate to the ethanol fermentation is provided by treating the hydrolysate with a wood-based carbonized material. Thereby, it is possible to remove the fermentation inhibitory material or materials supposed to inhibit the fermentation contained in the hydrolysate to a concentration at which the fermentation is not affected. Preferable polysaccharide biomass is a lignocellulose, e.g. wood powder of Japanese cedar.
