Oceanicella

The genus Oceanicella comprises one species named Oceanicella actignis. Members of this species possess pleomorphic cells ranging from rods to coccoid forms. The type strain of the species is nonmotile; some strains are motile. Cells stain Gram-negative and endospores are not observed. Colonies are nonpigmented. The species O. actignis is slightly thermophilic, slightly halophilic and strictly aerobic. Possess cytochrome c oxidase and is catalase positive. Chemoorganotrophic. Growth factors are not necessary for growth in minimal defined medium. Organic acids, amino acids and polyols are used as carbon and energy sources; sugars are not assimilated. Major respiratory quinone is ubiquinone 10 (U-10). Major polar lipids are phosphatidylcholine (PC), phosphatidylglycerol (PG) and one unidentified aminolipid (AL1). Fatty acids are primarily straight-chain. Isolated from marine and terrestrial saline hot springs. DNA G+C content is 71.2–72.4 mol% (HPLC and genome sequence). The type species is Oceanicella actignis. The genus belongs to the family Rhodobacteraceae.
