| Abstract |
A Gram-negative, aerobic, motile by flagella, and light yellow bacterium, designated SS1-76T, was isolated from sediment of the Nakdong River in Sangju-si, Republic of Korea. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate SS1-76T belongs to the genus Uliginosibacterium of the family Rhodocyclaceae, exhibiting high sequence similarity with the type strains of Uliginosibacterium gangwonense 5YN10-9T (96.0%) and Uliginosibacterium paludis KBP-13T (94.9%). Strain SS1-76T contains ubiquinone-8 as a respiratory quinone and summed feature 3 (C16:1 ω7c and/or C16:1 ω6c), C16:0, and C14:0 as major fatty acids. The cellular polar lipids are composed of phosphatidylethanolamine, phosphatidylglycerol, and unidentified aminophospholipids. The DNA G+C content was 65.3 mol%. Phenotypic, chemotaxonomic, and phylogenetic evidence clearly indicated that strain SS1-76T represents a novel species of the genus Uliginosibacterium, for which the name Uliginosibacterium sangjuense sp. nov. is proposed. The type strain is SS1-76T (= KCTC 52159T = JCM 31375T).
