A process includes providing a gaseous substrate comprising COto a bioreactor; providing acetogenic bacteria and medium to the bioreactor to provide a fermentation broth; providing sodium ions to the bioreactor through one or more sodium ion sources; fermenting the gaseous substrate with the acetogenic bacteria in the fermentation broth to produce one or more organic acids; and controlling a butyric acid to an acetic acid ratio by controlling the pH of the fermentation broth. In one aspect, butyric acid to acetic acid ratio increases when the pH of the fermentation broth decreases, and the ratio of butyric acid to acetic acid concentration decreases when the pH of the fermentation broth increases. The acetogenic bacteria includes a sodium translocating ATPase that is active during fermentation in the bioreactor. The sodium ions are provided so that Nais maintained between 1000 to 11000 ppm (g/g) in culture broth.

Process for controlling organic acid ratios in a carbon dioxide bioconversion process

A process is provided for management of ethanol concentration during syngas fermentation. A process for fermentation of syngas includes inoculating a medium to provide an inoculated medium. Inoculated medium is contacted with syngas and cells and medium are removed and separated to provide concentrated cells and permeate. Ethanol is separated from the permeate to provide ethanol and a reduced ethanol aqueous stream. The reduced ethanol aqueous stream is returned to the fermentation.
