Terrimonas arctica sp nov., isolated from Arctic tundra soil

A novel, Gram-stain-negative, aerobic, non-motile and rod-shaped bacterium, designated R9-86(T), was isolated from tundra soil collected near Ny-Alesund, Svalbard Archipelago, Norway (78 degrees N). Growth occurred at 4-28 degrees C (optimum, 22-25 degrees 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(T) belonged to the genus Terrimonas in the family Chitinophagaceae. 16S rRNA gene sequence similarities between strain R9-86(T) and the type strains of species of the genus Terrimonas with validly published names ranged from 93.7 to 95.0%. Strain R9-86(T) contained iso-C-15:1-G (25.7%), iso-C-15:0 (24.5%), iso-C-17:0-3OH (18.3%) and summed feature 3 (C-16:1 omega 7c and/or C-16:1 omega 6c, 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(T) 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 R9-86(T) (=CCTCC AB 2011004(T)=NRRL B-59114(T)).
