Abstract

[Problem to be Solved]Provided is a method which allows, for example, suppression of foaming in the purification step such as distillation and continuous operation, as well as direct treatment of a waste liquid (can liquid) without having to subject the same to an extra purification treatment by removing the microorganisms, nitrogen compounds, and phosphorous compounds at once from an organic substance-containing liquid obtained from microbial fermentation[Means to Solve the Problem]Disclosed is a method for producing an organic substance, comprising:a microbial fermentation step of obtaining a first organic substance-containing liquid comprising an organic substance, a nitrogen compound, a phosphorous compound, and microorganisms by microbial fermentation;a separation step of heating the first organic substance-containing liquid and separating into a liquid or solid component comprising the nitrogen compound, the phosphorous compound, and the microorganisms and a gaseous component comprising the organic substance;a liquefaction step of liquefying the gaseous component comprising the organic substance by condensation to obtain a second organic substance-containing liquid comprising the organic substance, anda second purification step of separating a distillate comprising the organic substance and a second can liquid from the second organic substance-containing liquid, whereinthe concentration of the nitrogen compound in the second can liquid is 0 to 150 ppm based on the total mass of the second can liquid, and the concentration of the phosphorous compound in the second can liquid is 0 to 5 ppm based on the total mass of the second can liquid.
