Abstract The strict anaerobe Desulfuromonas acetoxidans can oxidize acetate to CO2 with elemental sulfur as electron acceptor. 14C-labelling experiments and enzyme studies are described revealing that acetate oxidation proceeds via the citric acid cycle with the synthesis of oxaloacetate from acetate and 2 CO2 via pyruvate as anaplerotic reaction. An oxidation of acetate via one carbon unit intermediates as proposed for anaerobic bacteria fermenting acetate to 2 CO2 and 4 H2 was excluded.
