Background Hydrogenobacter thermophilus (strain DSM 6534 / IAM 12695 / TK-6) is a strictly thermophilic, obligate chemoautotrophic and hydrogen-oxidizing Gram-negative bacterium isolated from a hot spring located in Mine, Izu, Japan. Phylogenetic analysis based on the 16S ribosomal DNA sequence show that the strain is the deepest branching point among the Bacteria. In accordance with this, distinctive characteristics, such as unusual composition of cellular fatty acids (C18:0 and C20:1 as major fatty acids), a novel sulfur-containing quinone called methionaquinone and a characteristic carbon anabolism (via the reductive tricarboxylic acid cycle), have been reported. Moreover, it is able to assimilate ammonium using glutamine synthetase (GS). Its optimal growth temperature is around 70 to 75 degrees Celsius.
