A novel sulfate-reducing bacterium was isolated from a well that collected water from a deep aquifer at a depth of 430 m in the Paris Basin, France. The strain, designated B7-43T, was made up of vibrioid cells that were motile by means of a single polar flagellum. Cells contained desulfoviridin. In the presence of sulfate, the following substrates were used as energy and carbon sources: lactate, pyruvate, malate, fumarate, ethanol, butanol, acetate/H2 and glycine. Sulfite and thiosulfate were also used as electron acceptors in the presence of lactate. In the absence of electron acceptors, pyruvate, malate and fumarate were fermented. Optimal growth was obtained in 1 g NaCl l(-1) and at pH 7. On the basis of 16S rRNA gene sequence analysis, the isolate was most closely related to members of the genus Desulfovibrio (90 % similarity). It is thus proposed that strain B7-43T (=DSM 16056T=ATCC BAA-905T) represents a novel species within this genus, Desulfovibrio putealis sp. nov.
