Cells are straight or curved rods, are motile by means of polar flagella, and multiply by binary fission. Gram negative and belonging to the Betaproteobacteria. Internal membrane systems are poorly developed or absent. Photosynthetic pigments are bacteriochlorophyll a and carotenoids of the spheroidene series. Ubiquinones and menaquinones with eight isoprene units (Q-8 and MK-8) are present. Straight-chain C16:1 and C16:0 are the major components of cellular fatty acids. C10:0 3OH is present.The mol% G + C of the DNA is: 70.5–72.4 (Bd), 71.2–72.1 (HPLC). Type species: Rubrivivax gelatinosus
