Strain CPCC 100056T, which was isolated from a soil sample collected from the Qinghai–Tibet plateau, China, was subjected to a polyphasic taxonomic study. The organism was coccobacillus-shaped, non-motile and formed vinaceous colonies on ISP2 agar medium. The respiratory quinone was ubiquinone-10. The major fatty acids were C18 : 1
7c and C16 : 1
7c and/or C16 : 1
6c. The G+C content of the genomic DNA was 67.3 mol%. A comparison of sequences in GenBank revealed that strain CPCC 100056T exhibited highest 16S rRNA gene sequence similarity (84.5–95.5 %) with Roseomonas species. Strain CPCC 100056T could be distinguished from all Roseomonas species with validly published names by differences in phenotypic and genotypic properties. In view of the combined phenotypic, chemotaxonomic and phylogenetic data, strain CPCC 100056T should be classified as a representative of a novel species in the genus Roseomonas, Roseomonas vinacea sp. nov.; the type strain is CPCC 100056T (=KCTC 22045T =CCM 7468T).
These authors contributed equally to this work. The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain CPCC 100056T is EF368368.
Cellular fatty acid profiles of strain CPCC 100056T and type strains of related species are available as supplementary material with the online version of this paper.
