| Abstract | A novel anaerobic thermophilic sulfate-reducing bacterium designated LINDBHT1 was isolated from an anaerobic treating abattoir wastewaters digestor in Tunisia. Strain LINDBHT1 grew at temperatures between 50 and 65°C (optimum 55-60°C), and at pH between 5.9 and 9.2 (optimum pH 6.0-6.8). Strain LINDBHT1 required salt for growth (1-40 g NaCl l-1), with an optimum at 20-30g/L. In the presence of sulfate as terminal electron acceptor, strain LINDBHT1 used H2/CO2, propanol, butanol and ethanol as carbon and energy sources but fumarate, formate, lactate and pyruvate were not utilized. Butanol was converted to butyrate, while propanol and ethanol were oxidized to propionate and acetate, respectively. Sulfate, sulfite and thiosulfate were utilized as terminal electron acceptors but elemental sulfur, iron (III), fumarate, nitrate and nitrite were not used. The G+C content of the genomic DNA was 44.4 mol %. Phylogenetic analysis of the small-subunit (SSU) ribosomal RNA (rRNA) gene sequence indicated that strain LINDBHT1 was affiliated to the genus Desulfotomaculum with Desulfotomaculum halophilum and Desulfotomaculum alkaliphilum as its closest phylogenetic relatives (about 89% of similarity). This bacterium will constitute a new species of the genus Desulfotomaculum, Desulfotomaculum peckii (the type strain LINDBHT1T = DSM 23769T = JCM 17209T). |
