| 摘要: | A Gram-staining-negative bacterium, strain X14M-14(T), was isolated from a salt lake (Lake Xiaochaidan) in Qaidam basin, Qinghai Province, China. Its taxonomic position was determined by using a polyphasic approach. Cells of strain X14M-14(T) were non-spore-forming, non-motile rods. Strain X14M-14(T) was strictly heterotrophic and aerobic, catalase-positive and oxidase-negative. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain X14M-14(T) belonged to the family Flavobacteriaceae and formed a distinct lineage that was independent of the most closely related genera: Aequorivita (16S rRNA gene sequence similarities, 91.8-93.1 %) and Salinimicrobium (91.5-92.4 %). Strain X14M-14(T) contained MK-6 as the major respiratory quinone, and phosphatidylethanolamine and two unknown lipids as the major polar lipids. The major cellular fatty acids were iso-C-15 : 0, iso-C-15 : 1 G and isoC(17) (: 0) 3-OH. The presence of iso-C-15 : 1 G as a predominant fatty acid could distinguish this strain clearly from the most closely related genera in the family Flavobacteriaceae. The DNA G+C content was 36.6 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain X14M-14(T) represents a novel genus and species of the family Flavobacteriaceae, for which the name Planktosalinus lacus gen. nov., sp. nov. is proposed. The type strain is X14M-14(T) (=CGMCC 1.12924(T) =KCTC 42675(T)). |
