Abstract: A novel heterotrophic, thermophilic bacterium, designated strain AC55T, was isolated from a deep-sea hydrothermal vent chimney at the Hatoma Knoll in the Okinawa Trough, Japan. Cells of strain AC55T were non-motile, long rods (2.0-6.8μm long and 0.3-0.6μm wide). The strain was an obligatory anaerobic heterotroph capable of fermentative growth on complex proteinaceous substances. Elemental sulfur was reduced to hydrogen sulfide but did not stimulate growth. Growth was observed between 37 and 60℃ (optimum 55℃), pH 5.5 and 8.5 (optimum pH 6.6), and in the presence of 1.5-4.5% (w/v) NaCl (optimum 2.5%, w/v). Menaquinone-7 and -8 were the major respiratory quinones. The G + C content of the genomic DNA from strain AC55T was 51.6 mol%. The 16S rRNA gene sequence analysis revealed that strain AC55T was the first cultivated representative of Acidobacteria subdivision 10. Based on the physiological and phylogenetic features of the novel isolate, the genus name Thermotomaculum gen. nov. is proposed, with Thermotomaculum hydrothermale sp. nov. as the type species. The type strain is AC55T (=JCM 17643T = DSM 24660T = NBRC 107904T).
