1. Production of C by anaerobic fermentation with a carboxymophilic microorganism producing at least one of ethanol or butanol2And C4A process for oxygenates, the process comprising:

  • (a) providing a sulfur additive comprising s (ii) -s (iv) an inorganic sulfur compound that produces oxyanions of sulfur in an aqueous fermentation medium, (b) contacting a microbial culture of a microorganism with a substrate comprising carbon monoxide and maintaining the microbial culture in an aqueous fermentation medium comprising the sulfur additive and having a pH of less than 5.3, and (C) recovering one or more C'"'"'s from the fermentation medium2An oxygenate.
