A Gram stain-negative, yellowish green-pigmented, facultatively
anaerobic, motile, curved rod-shaped bacterium designated
as strain JJ016T was isolated from an artificial lake in
South Korea, and characterized using a polyphasic approach.
The 16S rRNA gene sequence of strain JJ016T indicated that
the isolate belonged to the family Rhodocyclaceae and exhibited
95.0% identity to Uliginosibacterium gangwonense
5YN10-9T. The major cellular fatty acids of the novel strain
were summed feature 3 (C16:1 ω6c and/or C16:1 ω7c), C16:0, C14:0,
and summed feature 8 (C18:1 ω7c and/or C18:1 ω6c). The DNA
G+C content of strain JJ016T was 61.9 mol%. The major respiratory
quinone and major polar lipid of strain JJ016T were
ubiquinone-8 and phosphatidylethanolamine, respectively.
Based on the morphological and physiological properties and
the biochemical evidence presented, we concluded that strain
JJ016T represents a novel species of a new genus in the family
Rhodocyclaceae, for which the name Viridibacterium curvum
gen. nov., sp. nov. is proposed. The type strain is JJ016T
(=KACC 16899T =JCM 18715T).
