Rho.do.cy' clus. Gr. n. rhodon the rose; Gr. n. cyclos a circle; M.L. masc. n. Rhodocyclus red circle.

Proteobacteria / Betaproteobacteria / Rhodocyclales / Rhodocyclaceae / Rhodocyclus

Cells are slender, curved, or straight, thin rods. Motile by means of polar flagella or nonmotile. Multiply by binary fission. Gram negative, belonging to class Betaproteobacteria . Internal photosynthetic membranes may appear as small, single, finger-like intrusions of the cytoplasmic membrane or may be absent. Photosynthetic pigments are bacteriochlorophyll a and carotenoids. Contain ubiquinones and menaquinones with eight isoprene units (Q-8 and MK-8). Straight-chain C16:1 and C16:0 acids are the major components of cellular fatty acids. C10:0 3OH is present.

The mol% G + C of the DNA is: 64.1–65.1.

Type species: Rhodocyclus purpureus Pfennig 1978, 285
