Firmicutes / “Clostridia” / Halanaerobiales / Halobacteroidaceae / Acetohalobium

Rod-shaped cells. Motile with 1–2 subterminal flagella. Multiplication by binary fission is by constriction rather than septation. Gram-stain-negative cell wall structure. Thermoresistant endospores formed by some strains. Strictly anaerobic. Possess a respiratory type of homoacetogenic metabolism. Extremely halophilic, growing at 1.7–4 M NaCl. Obligately dependent on sodium chloride. Neutrophilic. Mesophilic. Metabolism variable; lithoheterotrophic, utilizing hydrogen, formate, and carbon monoxide, methylotrophic, utilizing methylamines and betaine, or chemo-organotrophic, fermenting some amino acids and organic acids. Acetate is the end product with all substrates utilized.

DNA G+C content (mol%): 33–35 (T m).

Type species: Acetohalobium arabaticum Zhilina and Zavarzin 1990b, 470VP (Effective publication: Zhilina and Zavarzin 1990c, 747.).
