title: Qipengyuania sediminis gen. nov., sp. nov., a member of the family Erythrobacteraceae isolated from subterrestrial sediment.
abstract: A Gram-reaction-negative, non-motile, facultatively aerobic bacterium, designated strain M1T, was isolated from a subterrestrial sediment sample of Qiangtang Basin in Qinghai-Tibetan plateau, China. The strain formed rough yellow colonies on R2A plates. Cells were oval or short rod-shaped, catalase-positive and oxidase-negative. Phylogenetic analyses based on 16S rRNA gene sequences indicated that the isolate belonged to the family Erythrobacteraceae and showed 96.2–96.4 % 16S rRNA gene sequence similarities to its closest relatives. Chemotaxonomic analysis revealed ubiquinone-10 (Q10) as the dominant respiratory quinone of strain M1T and C17 : 1ω6c (44.2 %) and C18 : 1ω7c (13.7 %) as the major fatty acids. The major polar lipids were phosphatidylethanolamine, phosphatidylcholine, phosphatidylglycerol, diphosphatidylglycerol, sphingoglycolipid, three unidentified glycolipids, one unidentified phosphoglycolipid and one unidentified lipid. The DNA G+C content of strain M1T was 73.7 mol%. On the basis of phenotypic, phylogenetic and genotypic data presented in this study, strain M1T represents a novel species of a new genus in the family Erythrobacteraceae, for which the name Qipengyuania sediminis gen. nov., sp. nov. is proposed. The type strain of the type species is M1T ( = CGMCC 1.12928T = JCM 30182T).
