Isolation and characterization of Desulfovibrio burkinensis sp. nov. from an !african ricefield, and phylogeny of Desulfovibrio alcoholivorans Ouattara, A.S. Patel, B.K.C. /Cayol, Jean-Luc Cuzin, N. Traore, A.S. /Garcia, Jean-Louis BACTERIE ESPECE NOUVELLE FERMENTATION SULFATOREDUCTION ANAEROBIOSE PHYLOGENIE TAXONOMIE RIZIERE BIOLOGIE MOLECULAIRE A sulfate-reducing bacterium, strain HDvT (T = type strain), was isolated from an anoxic ricefield soil. Cells were Gram-negative, non-sporulating curved rods motile by means of a single polar flagellum. Cytochrome c3 and desulfoviridin were present. In the presence of sulfate, glycerol, 1,2- and 1,3-propanediol, dihydroxyacetone, pyruvate, lactate, fumarate, maleate, malate and succinate were incompletely oxidized mainly to acetate. Sulfite, thiosulfate, elemental sulfur, furmarate, maleate, malate and dihydroxyacetone were fermented. The DNA base composition was 67mol% G+C. The phylogenetic, phenotypic and physiological characteristics of strain HDvT indicate that is is a new species of the genus Desulfovibrio, for which the name Desulfovibrio burkinensis sp. nov. is proposed ; the type strain is HDvT (= DSM 6830T). Phylogenetic analysis confirmed that Desulfovibrio alcoholivorans was a distinct species supporting the previously published phenotypic data.
