Nitrate is reduced to nitrite. Ferments fumarate, malate and pyruvate. Elemental
sulfur, thiosulfate, sulfite, dithionite, DMSO, nitrate and arsenate can serve as electron
acceptors. Lactate, fumarate, pyruvate, succinate and malate can be used as electron
donors. Hydrogen and formate can serve as electron donors when acetate is used as
