Roseomonas terrae sp. nov

Int J Syst Evol Microbiol. 2007 Nov;57(Pt 11):2485-2488. doi: 10.1099/ijs.0.65113-0.


A Gram-negative, non-motile, coccobacilli-shaped bacterium, DS-48T, was isolated from soil from Dokdo, Korea, and its taxonomic position was investigated by means of a polyphasic study. Strain DS-48T grew optimally at 25 degrees C and pH 7.0-8.0 in the presence of 0.5% (w/v) NaCl. It contained Q-10 as the predominant ubiquinone and C18:1omega7c and C18:1 2-OH as the major fatty acids. The DNA G+C content was 69.3 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain DS-48T fell within the genus Roseomonas, clustering with Roseomonas lacus TH-G33T (at a bootstrap confidence level of 100%). The levels of similarity between the 16S rRNA gene sequence of strain DS-48T and those of the type strains of recognized Roseomonas species were in the range 93.2-98.0%. DNA-DNA relatedness data and differential phenotypic properties, together with the phylogenetic distinctiveness of DS-48T, revealed that this strain differs from recognized Roseomonas species. On the basis of phenotypic, phylogenetic and genetic data, therefore, strain DS-48T represents a novel species within the genus Roseomonas, for which the name Roseomonas terrae sp. nov. is proposed. The type strain is DS-48T (=KCTC 12874T=JCM 14592T).
