Abstract

An object of the present invention is to provide a means for conveniently producing ethanol with high efficiency from a carbon source derived from a plant biomass resource or the like. The present invention relates to a method for producing ethanol, comprising a step of generating ethanol by culturing basidiomycetes belonging to the genus Phlebia with a carbon source. As carbon sources, cellulose, hemicellulose, glucose, xylose, and the like or plant biomass resources containing the same can be used.

Claims

1. A method for producing ethanol comprising:

a pretreatment step for culturing a basidiomycete belonging to the genus Phlebia with a carbon source under aerobic conditions; and

a fermentation step for further culturing the basidiomycete with the carbon source under semi-aerobic conditions or anaerobic conditions after the pretreatment step, so as to generate ethanol,

wherein the pretreatment step and the fermentation step are performed within the same reactor.

2. The method according to claim 1, wherein the basidiomycete belonging to the genus Phlebia is Phlebia sp. MKFC40001 (NITE BP-1099).

3. The method according to claim 1, wherein the carbon source is a polysaccharide.

4. The method according to claim 3, wherein the polysaccharide is in the form of a plant biomass material, crystalline cellulose, paper, pulp, or cotton linter.

5. The method according to claim 1, wherein the carbon source is at least one type of saccharides selected from the group consisting of glucose, xylose, mannose, galactose, fructose, and arabinose.
