Abstract

A novel, Gram-stain-negative, aerobic, non-motile and rod-shaped bacterium, designated R9-86, was isolated from tundra soil collected near Ny-Ålesund, Svalbard Archipelago, Norway (78° N). Growth occurred at 4–28 °C (optimum, 22–25 °C) and at pH 6.0–9.0 (optimum, pH 7.0). Flexirubin-type pigments were absent. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain R9-86 belonged to the genus in the family . 16S rRNA gene sequence similarities between strain R9-86 and the type strains of species of the genus with validly published names ranged from 93.7 to 95.0 %. Strain R9-86 contained iso-C-G (25.7 %), iso-C (24.5 %), iso-C-3OH (18.3 %) and summed feature 3 (Cω7 and/or Cω6, 8.7 %) as its major cellular fatty acids; phosphatidylethanolamine and an unknown polar lipid as its main polar lipids, and MK-7 as its predominant respiratory quinone. The DNA G+C content was 48.4 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain R9-86 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is R9-86 ( = CCTCC AB 2011004 = NRRL B-59114).
