Phylum Proteobacteria, Class Gammaproteobacteria, Order Pseudomonadales, Family Pseudomonadaceae, Genus Pseudomonas,
Pseudomonas xanthomarina Romanenko et al. 2005.
Gram-negative, rod-shaped bacteria, 1.6-1.8 mm long and 0.2-0.3 μm in diameter,
motile by means of a single polar flagellum.
On nutrient agar media yellow-orange-pigmented smooth translucent colonies 3-5
mm in diameter are formed. Pyocyanin or fluorescent pigment production was not
observed on King A or King B media, respectively. The strain grows in 0–8% NaCl at
4-37 ºC, does not grow in 10% NaCl or at 40-41 ºC.
Isolated from the ascidian Halocynthia aurantium from coastal waters of The Sea of Japan, Russia.
Resistant to benzylpenicillin 10 U.
