A novel psychrotolerant bacterium, designed strain M6-79T, was isolated from an arctic glacial foreland soil sample collected from Ny-Ålesund in the Svalbard Archipelago, Norway. Cells of strain M6-79T were Gram-stain-negative, rod-shaped and produced a red-pigment. Strain M6-79T was strictly aerobic, non-motile, non-endospore-forming, oxidase-negative and catalase-positive. Based on 16S rRNA gene sequence analysis, strain M6-79T was phylogenetically related to Roseomonas aquatica TR53T (95.2 % 16S rRNA gene sequence similarity), Roseomonas lacus TH-G33T (94.3 %), 'Roseomonas sediminicola' FW-3 (94.3 %), Roseomonas terrae DS-48T (94.1 %) and Roseomonas soli 5N26T (94.1 %). The unique isoprenoid quinone detected in strain M6-79T was Q-9. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, one unknown aminolipid and one unknown lipid. Strain M6-79T possessed C18 : 1ω7c, C16 : 0 and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) as the predominant fatty acids, and the DNA G+C content was 71.2 mol%. Combined data from phylogenetic, phenotypic and chemotaxonomic studies revealed that strain M6-79T represents a novel species of the genus Roseomonas, for which the name Roseomonas arctica sp. nov. is proposed. The type strain is strain M6-79T ( = CCTCC AB 2013101T = LMG 28251T).
