A novel, Gram-stain-negative, aerobic, non-motile and rod-shaped bacterium, designated R9-86T, 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 R9-86T belonged to the genus Terrimonas in the family Chitinophagaceae. 16S rRNA gene sequence similarities between strain R9-86T and the type strains of species of the genus Terrimonas with validly published names ranged from 93.7 to 95.0 %. Strain R9-86T contained iso-C15 : 1-G (25.7 %), iso-C15 : 0 (24.5 %), iso-C17 : 0-3OH (18.3 %) and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c, 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 R9-86T is considered to represent a novel species of the genus Terrimonas, for which the name Terrimonas arctica sp. nov. is proposed. The type strain is R9-86T ( = CCTCC AB 2011004T = NRRL B-59114T).
