Cells were spore-forming straight rods, motile by peritrichous flagella. The optimum growth conditions were 50 °C, pH 7·5 and 0·1 % NaCl. Strain 50-1 BONT fermented arabinose, cellobiose, fructose, galactose, glucose, mannose, sucrose, xylose and yeast extract. Glucose was fermented mainly into lactate, formate, hydrogen and CO2. The major end product of pyruvate fermentation was acetate together with H2 and CO2. Thiosulfate, sulfate, elemental sulfur and nitrate were not used as terminal electron acceptors. The DNA G+C content was 55·5 mol%. The closest phylogenetic relative of strain 50-1 BONT was Thermoanaerobacterium thermosulfurigenes (16S rRNA gene sequence similarity of 85·7 %). As strain 50-1 BONT was physiologically and phylogenetically different from members of the order ‘Thermoanaerobacteriales’, it is proposed that strain 50-1 BONT (=DSM 15567T=CIP 107919T) be classified as the type strain of a novel species of a new genus, Mahella australiensis gen. nov., sp. nov.", }
