Phylum Proteobacteria, Class Gammaproteobacteria, Order Pseudomonadales, Family Pseudomonadaceae, Genus Pseudomonas,
Pseudomonas umsongensis Kwon et al. 2003.
Gram-negative, nonspore-forming rods, 1 x 1.5 μm, motile by a single polar flagellum.
Colonies are circular and white-yellow on Luria Bertani agar. Cells produce a
fluorescent pigment on King B and PAF media. Grows at 4 ºC but not at 37 ºC. Growth
occurs in media supplemented with 5% NaCl, but not at a salinity higher than 7%.
Isolated from farm soil in Korea.
