The genus Pyrinomonas is represented by a single species, Pyrinomonas methylaliphatogenes. Cells are nonmotile, non‐spore‐forming rods. Gram‐negative, catalase‐ and oxidase‐positive. Cells divide by binary fission. Thermophilic and moderately acidophilic. Obligately aerobic and chemoheterotrophic. Growth on a limited selection of peptides, saccharides, and organic acids. Hydrogen is oxidized to subatmospheric concentrations when cells are carbon‐limited. The principal fatty acids are iso‐C15:0, iso‐C17:0, iso‐C19:0, and iso‐C21:0. Transmembrane and ether‐linked lipids, including iso‐diabolic acid and the glyceryl ethers of iso‐C15:0 and iso‐diabolic acid, comprise up to 40% of cell lipid extract. Primary cellular lipids are phosphatidylcholine and phosphatidylethanolamine. MK‐8 is the primary respiratory quinone and G + C content of 59.36 mol%. Members of the class Blastocatellia, family Pyrinomonadaceae. The type strain was isolated from geothermally heated soils in New Zealand.
