A Gram stain-negative, yellowish green-pigmented, facultatively anaerobic, motile, curved rod-shaped bacterium designated as strain JJ016 T was isolated from an artificial lake in South Korea, and characterized using a polyphasic approach. The 16S rRNA gene sequence of strain JJ016 T indicated that the isolate belonged to the family Rhodocyclaceae and exhibited 95.0% identity to Uliginosibacterium gangwonense 5YN10-9 T . The major cellular fatty acids of the novel strain were summed feature 3 (C 16:1 ω 6 c and/or C 16:1 ω 7 c ), C 16:0 , C 14:0 , and summed feature 8 (C 18:1 ω 7 c and/or C 18:1 ω 6 c ). The DNA G+C content of strain JJ016 T was 61.9 mol%. The major respiratory quinone and major polar lipid of strain JJ016 T were ubiquinone-8 and phosphatidylethanolamine, respectively. Based on the morphological and physiological properties and the biochemical evidence presented, we concluded that strain JJ016 T 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 JJ016 T (=KACC 16899 T =JCM 18715 T ).
