Gram-negative somewhat curved motile rods (0.6–0.8 × 1.5–3.6 µm). One polar flagellum. Chemoorganoheterotrophic and microaerophilic. Strictly respiratory; O2 and nitrate are electron acceptors. Oxidase positive. Fix N2 . Grow on acetate, ethanol, fumarate, L-glutamate, DL-lactate, L-malate, propionate, and succinate.
The mol% G + C of the DNA is: 64–65.
Type species: Azovibrio restrictus Reinhold-Hurek and Hurek 2000, 657.
