Phylum BVIII. Nitrospirae phy. nov.
The phylum Nitrospirae is based mainly on phylogenetic grounds. At present, it consists of a single class, order, and family of Bacteria and environtaxa that branch deeply in the major reference trees; member taxa consistently group together. Gram-negative, curved, vibrioid or spiral-shaped cells. Metabolically diverse, most genera are aerobic chemolithotrophs including nitrifiers, dissimilatory sulfate reducers, and magnetotactic forms. One genus (Thermodesulfovibrio) is thermophilic, and obligately acidophilic and anaerobic.
