Hydrogenovibrio marinus gen. nov., sp. nov., a Marine Obligately Chemolithoautotrophic Hydrogen-Oxidizing Bacterium

Abstract

The name Hydrogenovibrio marinus gen. nov., sp. nov. is proposed for an obligately chemolithoautotrophic, mesophilic, gram-negative, motile, comma-shaped, aerobic, hydrogen-oxidizing bacterium that was isolated from seawater. The optimum temperature and NaCl concentration for growth are 37°C and 0.5 M, respectively. The guanine-plus-cytosine content of the DNA is 44.1 mol%. The ubiquinone is ubiquinone-8, and the major cellular fatty acids are C16:0, C18:0, and C16:1 acids. The type strain of this species is strain MH-110 (= JCM 7688).
