Kinetic parameters of acetate oxidation were determined for the
sulfate reducers Desulforhabdus amnigenus and
Desulfobacca acetoxidans. Based on these parameters, both
sulfate reducers seem to be able to outcompete
Methanosaeta spp. for acetate in acetate-fed
anaerobic bioreactors. Mixed-substrate studies showed that
D. amnigenus degraded acetate
and hydrogen simultaneously but preferred lactate, propionate, and
ethanol over acetate.
