Niveibacterium umoris gen. nov., sp. nov., isolated from wetland freshwater

A taxonomic study was carried out on a novel bacterial strain, designated MIC2059 T , which was isolated from Ungok Wetland of Gochang in Korea. Cells of the isolate were found to be Gram-stain-negative, rod-shaped and motile. Comparison of the 16S rRNA gene sequences indicated that the isolate belonged to the family Rhodocyclaceae , with Uliginosibacterium gangwonense as its closest relative, with a similarity of 94.8 %. It contained summed feature 3 (comprising C 16 : 1 ω7 c and/or C 16 : 1 ω6 c ), C 16 : 0 , summed feature 8 (comprising C 18 : 1 ω7 c and/or C 18 : 1 ω6 c ) and C 12 : 0 3-OH as the major fatty acids and Q8 as the respiratory ubiquinone. The polar lipid profile of strain MIC2059 T revealed the presence of phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol as major polar lipids. In addition, phosphatidylserine, an unidentified aminophospholipid and unidentified lipids were present in small amounts. The DNA G+C content of the strain was 65.1 mol%. On the basis of the evidence presented, it is concluded that strain MIC2059 T represents a novel species of a novel genus within the family Rhodocyclaceae, for which the name Niveibacterium umoris gen. nov., sp. nov. is proposed. The type strain is MIC2059 T ( = KACC 17062 T  = JCM 18716 T ).
