J Microbiol. 2017 Aug;55(8):595-599. doi: 10.1007/s12275-017-7002-6. Epub 2017 Jul 28.


A Gram-negative, facultative anaerobic, rod-shaped, motile by means of a polar flagellum, greenish-yellow-pigmented bacterial strain (designated strain JJ3220T) was isolated from an artificial lake in South Korea and characterized using a polyphasic approach. The 16S rRNA gene sequence of strain JJ3220T indicated that the isolate belongs to the family Rhodocyclaceae, and that it exhibits 96.4% similarity to Uliginosibacterium paludis KBP-13T. The major cellular fatty acids of the novel strain were C14:0, C16:0, and summed feature 3 (C16:1 ω6c and/or C16:1 ω7c). Strain JJ3220T had flexirubin-type pigments. The DNA G+C content of the strain was 62.8%. The major respiratory quinone and major polar lipid of strain JJ3220T were ubiquinone-8 and phosphatidylethanolamine, respectively. Based on the morphological and physiological properties and biochemical evidence presented, it can be concluded that strain JJ3220T represents a novel species of the genus Uliginosibacterium. The type strain Uliginosibacterium flavum is JJ3220T (=KACC 17644T =JCM 19465T).
