Title:
METHOD FOR PRODUCING ORGANIC SUBSTANCE
Document Type and Number:
WIPO Patent Application WO/2019/188730
Kind Code:
A1
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 re-used 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.
