摘要: A Gram-positive-staining, aerobic, catalase- and oxidase-positive, irregular short rod-shaped actinobacterium, designated strain YIM C003(T), was isolated from a salt mine in Yunnan, PR China. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain YIM C003(T) was most closely related to strains of the genera Knoellia (94.2-96.0% similarity), Oryzihumus (95.6%), Terrabacter (94.9-95.4%), Janibacter (94.9-95.4%), Kribbia (95.0%), Lapillicoccus (95.0%) and Phycicoccus (94.2-95.0%) of the family Intrasporangiaceae and that it formed an independent monophyletic lineage with three strains of Oryzihumus leptocrescens. The DNA G+C content of strain YIM C003(T) was 72.0 mol%. The diagnostic cell-wall diamino acid was meso-diaminopimelic acid. The predominant menaquinone was MK-8(H-4). Mycolic acids were not detected. The polar lipids were diphosphatidylglycerol, phosphaticlylglycerol, phosphatidylethanolamine, phosphatidylinositol and two unknown phospholipids. The major cellular fatty acids were C-18:1 omega 9c and C-16:0. These chemotaxonomic properties, together with data from phylogenetic analysis, enabled the novel isolate to be differentiated from all other members of the family. A novel species in a new genus, Fodinibacter luteus gen. nov., sp. nov., is proposed, with strain YIM C003(T) (=DSM 21208(T) =CCTCC AA 208036(T)) as the type strain of Fodinibacter luteus.
