Abstract: Provided is a method for producing an organic substance, in which an organic material (metabolite) derived from a microorganism is reduced while retaining a nutritive substance in an organic substance-containing solution discharged from a fermentation tank containing the microorganism, whereby various nutritional elements contained in the organic substance-containing solution can be reused with high efficiency. A method for producing an organic substance by the microbial fermentation of a synthetic gas containing at least carbon monoxide, the method comprising a synthetic gas supply step of supplying the synthetic gas into a fermentation tank containing a microorganism, a fermentation step of subjecting the synthetic gas to microbial fermentation in the fermentation tank, an aerobic fermentation treatment step of subjecting at least a portion of a liquid produced in the fermentation step to an aerobic fermentation treatment in a liquid waste treatment unit, and a recycling step of supplying a liquid produced in the aerobic fermentation treatment step to the fermentation tank, wherein the aerobic fermentation treatment step is carried out in the presence of a nitrifying bacterium inhibitor.

Abstract: Provided is a method for determining origin of carbon source of chemical substance, which makes it possible to determine whether resource-recycled carbon is used as a carbon raw material from a chemical substance in various goods. The method for determining origin of carbon source of chemical substance includes: a step S1 of acquiring a carbon-14 content rate R1 of a standard chemical substance having carbon element in which carbon has been recycled as a resource; a step S2 of acquiring a carbon-14 content rate R2 of a chemical substance to be identified; a step S3 of calculating a ratio (R2/R1) of the content rate R2 to the content rate R1; and a step S4 of determining that a carbon raw material in the chemical substance to be identified contains resource-recycled carbon based on the ratio (R2/R1).
