acetoxidans DSM 684 converts free elemental sulfur to sulfide. Interesting
issues are how the bacteria acquire the elemental sulfur granules and transport
the sulfur for conversion to sulfide. Like the sulfate reducers (see D.
desulfuricans), sulfide production is toxic and can have important
economic consequences. Anaerobic oxidation of acetate, ethanol and propanol
by reduction of elemental sulfur to sulfide.
