摘要： A Gram-negative, rod-shaped, facultatively anaerobic, halotolerant bacterial strain, designated YIM YD3(T), was isolated from a salt mine in Yunnan, south-west China. The taxonomy of strain YIM YD3(T) was investigated by a polyphasic approach. Strain YIM YD3(T) was motile, formed pink colonies and was positive for catalase and oxidase activities. Q-10 was the predominant respiratory ubiquinone. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylcholine and two unknown phospholipids. The major fatty acids (>10% of total fatty acids) were C(18:1)omega 7c, C(18:1)omega 9c, C(16:0) and C(19:0) cyclo omega 8c. The DNA G + C content was 71.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparisons showed that the isolate formed a distinct line within a clade containing the genera Balneimonas, Bosea, Chelatococcus and Microvirga in the order Rhizobiales, with highest levels of 16S RNA gene sequence similarity to the type strain of Balneimonas flocculans (93.5%). On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain YIM YD3(T) represents a novel species in a new genus, for which the name Salinarimonas rosea gen. nov., sp. nov. is proposed, with strain YIM YD3(T) (=KCTC 22346(T) =CCTCC AA208038(T)) as the type strain.
