Qipengyuania sediminis gen. nov., sp nov., a member of the family Erythrobacteraceae isolated from subterrestrial sediment

A Gram-reaction-negative, non-motile, facultatively aerobic bacterium, designated strain M-1(T), 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 (010) as the dominant respiratory quinone of strain M1(T) and C-17 : (1)omega 6c (44.2 %) and C-18 : 1 omega 7c (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 M1(T) was 73.7 mol%. On the basis of phenotypic, phylogenetic and genotypic data presented in this study, strain M1(T) represents a novel Species Of a new geniis in the family Erythrobacteraceae, for which the name Qipengyuania sediminis gen. nov., sp. nov. is proposed. The type strain of the type species is M1(T) (=CGMCC 1.42928(T)=JCM 30182(T)).
