Abstract

A novel sulfate-reducing bacterium designated strain BE2801 was isolated from oil-polluted estuarine sediments (Berre Lagoon, France). Cells were Gram-stain-negative, motile, slightly curved or vibrioid rods. Optimal growth of strain BE2801 occurred at 30–32 °C, 0.5–1.5% NaCl (w/v) and pH 7.2–7.4. Strain BE2801 grew with C to C fatty acids or C to C -alkenes as electron donors. Acetate and carbon dioxide were the oxidation products. The major cellular fatty acids were C, Cω7 and Cω7. The DNA G+C content was 50.2 mol%. 16S rRNA and gene sequence analysis indicated that strain BE2801 was a member of the family within the class . DNA–DNA hybridization with the most closely related taxon demonstrated 14.8 % relatedness. Based on phenotypic and phylogenetic evidence, strain BE2801 ( = DSM 25524 = JCM 18157) is proposed to be a representative of a novel species of the genus , for which the name sp. nov. is suggested.
