title: Desulfatiferula olefinivorans gen. nov., sp. nov., a long-chain n-alkene-degrading, sulfate-reducing bacterium.
abstract: A novel anaerobic, long-chain alkene-degrading, sulfate-reducing bacterium, strain LM2801T, was isolated from brackish sediment of a wastewater decantation facility of an oil refinery (Berre lagoon, France). Cells of strain LM2801T were Gram-negative, motile, slightly curved or vibrioid rods. Its optimum growth conditions were 30-36 degrees C, 6-10 g NaCl l(-1) and pH 7.5. Strain LM2801T incompletely oxidized long-chain alkenes (from C14 to C23) and fatty acids (C14 to C24). The DNA G+C content was 45.5 mol%. Sequence analyses of the 16S rRNA and dsrAB genes indicated that the strain was a member of the family Desulfobacteraceae within the Deltaproteobacteria. This novel isolate possesses phenotypic and phylogenetic traits that do not allow its classification as a member of any previously described genus. Therefore, strain LM2801T is described as a member of a new genus, Desulfatiferula gen. nov., of which Desulfatiferula olefinivorans sp. nov. is the type species. The type strain of Desulfatiferula olefinivorans is LM2801T (=DSM 18843T=JCM 14469T).
