| Popis: | A pale yellow, Gram-reaction-negative, non-motile, aerobic bacterium, designated MC 3726T, was isolated from a tundra soil near Ny-Ålesund, Svalbard Archipelago, Norway (78 °N). Growth occurred at 4–37 °C (optimum 25–30 °C) and at pH 5.0–9.0 (optimum pH 8.0). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain MC 3726T belonged to the genus Luteolibacter in the family Verrucomicrobiaceae. The 16S rRNA gene sequence of this strain showed 93.18, 92.54 and 92.44 % similarity to those of Luteolibacter cuticulihirudinis E100T, Luteolibacter pohnpeiensis A4T-83T and Luteolibacter yonseiensis EBTL01T, respectively. The cell wall of strain MC 3726T contained meso-diaminopimelic acid as the diagnostic amino acid. Strain MC 3726T contained iso-C14:0 (38.28 %), C16:0 (15.89 %), C16:1ω9c (14.24 %), iso-C16:0 (10.42 %) and anteiso-C15:0 (5.75 %) as the predominant cellular fatty acids, MK-9 and MK-10 as the major respiratory quinones, and phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylglycerol and diphosphatidylglycerol as the main polar lipids. The DNA G+C content was 60.7 mol %. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain MC 3726T is considered to represent a novel species of the genus Luteolibacter, for which the name Luteolibacter arcticus sp. nov. is proposed. The type strain is MC 3726T ( = CCTCC AB 2014275T = LMG 28638T). An emended description of the genus Luteolibacter is also provided, along with emended descriptions of Luteolibacter cuticulihirudinis, Luteolibacter yonseiensis and Luteolibacter pohnpeiensis. |
