Abstract

Rho.do' bi.um. Gr. n. rhodon the rose; Gr. n. bios life; M.L. n. Rhodobium red life.

Proteobacteria / Alphaproteobacteria / Rhizobiales / Rhodobiaceae / Rhodobium

Cells are ovoid to rod shaped, motile by means of polar, subpolar or randomly distributed flagella; and cells multiply by budding and asymmetric cell division. Rosette formation is rare. Gram negative and belong to the Alphaproteobacteria . Phototrophically grown cells contain internal photosynthetic membranes as lamellar stacks parallel to the cytoplasmic membrane. Photosynthetic pigments are bacteriochlorophyll a and carotenoids of the spirilloxanthin series. Straight-chain saturated and monounsaturated C 18:1 and C18:0 are the major components of cellular fatty acids, with the former being predominant. Ubiquinones and menaquinones with 10 isoprene units (Q-10 and MK-10) are present as major quinones.

The mol% G + C of the DNA is: 61.5–65.7.

Type species: Rhodobium orientis Hiraishi, Urata and Satoh 1995d, 230.
