Cells of the novel isolate were rods, 0.3-0.8 mu m in width and 1.5-10 mu m in length, surrounded by a sheath-like structure (toga). Strain Rift-s3(T) grew at temperatures ranging from 44 to 75 degrees C, at pH 5.5 to 8.0, and with NaCI concentrations of 3 to 60 g l(-1). Under optimum conditions (65 degrees C, pH 6.0, NaCl 25 g I-1), the doubling time was 30 min. The isolate was able to ferment mono-, oligo- and polysaccharides including cellulose, chitin, xylan and: pectin, and proteins including beta-keratins, casein and gelatin. Acetate, hydrogen and carbon dioxide were the main products of glucose fermentation. The G +C content of the DNA was 30 mol%. Phylogenetic analysis of 16S rRNA gene sequences showed the affiliation of strain Rift-s3(T) with the genus Thermosipho, with Thermosipho atlanticus Ob7(T) as the closest relative (96.5% 16S rRNA gene sequence similarity). Based on the phylogenetic analysis and physiological properties of the novel isolate we propose a novel species of the genus Thermosipho, Thermosipho activus sp. nov., with Rift-s3(T) (=DSM 26467(T)=VKM B-2803(T)) as the type strain.
