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).
