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 Hans-Jürgen Rüger, a German microbiologist, for his contribution to the taxonomy of marine species of Agrobacterium.[2]
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
- are incapable of photosynthetic growth
- bacteriochlorophyll a is absent
- major quinone is ubiquinone 10
- mol% G+C of the DNA is 55–59
- 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 for 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]
