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. The processes involve subjecting a portion of the aqueous fermentation broth after recovery of the product oxygenated organic compound to anaerobic organic bioconversion, and recycling the broth for use in the bioconversion of syngas.
