sp. nov., isolated from high-Arctic tundra soil, and emended descriptions of and .

A yellow, Gram-reaction-negative, non-motile, aerobic bacterium, designated D07, was isolated from a tundra soil near Ny-Ålesund, Svalbard archipelago, Norway (78° N). Growth occurred at 4-37 °C (optimum 28-30 °C) and at pH 6.0-9.0 (optimum pH 7.0-8.0). The strain produced flexirubin-type pigments. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain D07 belonged to the genus in the family . The 16S rRNA gene sequence of this strain showed 93.83 and 93.31 % sequence similarity, respectively, to those of C26 and X-65. Strain D07 contained anteiso-C (25.91 %), iso-C (16.05 %), iso-C 3-OH (9.64 %), iso-C (9.42 %) and iso-C (7.36 %) as the predominant cellular fatty acids, MK-6 as the major respiratory quinone and phosphatidylethanolamine, five unknown aminolipids and three unknown lipids as the main polar lipids. The DNA G+C content was 49.3 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain D07 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is D07 ( = CCTCC AB 2011160 = KCTC 42897). Emended descriptions of and are also provided.
