It is medium-sized (0.6 to 0.8 μm) and possesses bipolar tufts of flagella. The guanine-plus-cytosine content of its deoxyribonucleic acid is 60 to 62 mol%. Based upon its source, morphology, and biochemical features, the organism belongs to the genus Aquaspirillum Hylemon et al. 1973. Because this organism does not closely resemble any of the previously described medium-sized aquaspirilla, it is proposed here as belonging to a new species, Aquaspirillum autotrophicum. The specific epithet refers to the outstanding property of this organism to grow on hydrogen and carbon dioxide as energy and carbon sources, respectively. The type strain of A. autotrophicum, strain SA 32, was deposited with the Deutsche Sammlung von Mikroorganismen under the number DSM 732. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-28-1-112
