Abstract (en)

[origin: WO2008123637A1] Disclosed herein is a method of producing ethanol from a beer-fermenting yeast waste solution. Ethanol is extracted by fractional distillation from a beer- fermenting yeast waste solution containing about 5-12% ethanol. Desirably, the beer- fermenting yeast waste solution, where ethanol has been extracted, is used as a culture solution in culturing and fermentation to produce cellulose. Then, the product is hydrolyzed and fermented into ethanol. Further, a method of producing ethanol by injecting biomass into a beer-fermenting yeast waste solution is disclosed.
