In taxonomy, Ruegeria is a genus of the Rhodobacteraceae.[1] This genus was formerly known as the marine Agrobacterium before they were reclassified in 1998. It bears in fact the name of Wolfgang Rüger, a German microbiologist, for his contribution to the taxonomy of marine species of Agrobacterium.[2]

[edit] Characteristics

The genus is characterised by members who are:[3]

  • Gram-negative — like all Proteobacteria
  • ovoid to rod-shaped cells 0.6–1.6 × 1.0–4.0 µm
  • Motile by polar flagella, or nonmotile
  • non-sporeformers
  • Aerobic
  • Oxidase and catalase positive
  • No photosynthetic growth
  • Bacteriochlorophyll a is absent — feature absent to Sulfitobacter, Sagittula, Octadecabacter, Ruegeria and Antarctobacter, but present in Roseobacter and to a lesser extent Staleya, Roseivivax and Roseovarius
  • Major quinone is ubiquinone 10 — common in most alphaproteobacteria and mitochondria, an organelle descending from the Rickettsiales (alphaproteobacteria)
  • The mol% G � C of the DNA is 55–59
  • the type species is R. altantica — unrelated to Pseudoalteromonas altantica, a gammaproteobacterium
  • member of the family Rhodobacteraceae, which is phenotypically, metabolically, ecologically diverse and defined based on 16S sequences data.

Phylogenetically it is very close to the genus Silicibacter, but the two remain separate species due to phenotypic differences — two species fo which this is problematic are Ruegeria lacuscaerulensis and Ruegeria pomeroyi.[4][5]

Two species that have been removed from the genus are Marinovum algicola (Ruegeria algicola) and Thalassobius gelatinovorus (Ruegeria gelatinovora).[6][and refs therein]
