The syntrophic propionate-oxidizing bacterium Syntrophobacter fumaroxidans possesses two distinct formate dehydrogenases and at least three distinct hydrogenases. All of these reductases are either loosely membrane-associated or soluble proteins and at least one of the hydrogenases is located in the periplasm. These enzymes were expressed on all growth substrates tested, though the levels of each enzyme showed large variations. These findings suggest that both H2 and formate are involved in the central metabolism of the organism, and that both these compounds may serve as interspecies electron carriers during syntrophic growth on propionate.
