Abstract
Processes are disclosed for economically and effectively removing co-produced oxygenated organic compound from an anaerobic, aqueous fermentation broth used for the bioconversion of syngas to product oxygenated organic compound. Nitrate anion is added to the broth and the broth is contacted with denitrifying microorganisms that bioconvert the nitrate and organic compounds in the broth to reduced nitrogen compound and carbon dioxide.
