Abstract: The present invention relates to a composition for producing 2,3-butanediol by using ethanol and synthetic gas and a 2,3-butanediol production method. A composition according to an aspect of the present invention includes ethanol as an active ingredient. In the case where a 2,3-butanediol production strain is inoculated into a medium containing the composition and cultured and a synthetic gas is added thereto, 2,3-butanediol, which is a biofuel and a chemical substance, can be economically produced with ethanol serving as a substrate. In the metabolism process, the carbon flux can be concentrated on the production route of the target material, whereby the composition has an excellent effect of increasing the production efficiency of 2,3-butanediol and enhancing the productivity of 2,3-butanediol by controlling only fermentation conditions such as amounts of the synthetic gas or ethanol and stirring speeds of the medium.
