sp. nov., isolated from Arctic tundra soil.

In the present paper, we describe a new species of the genus , designated as strain 1E403, which was isolated from a soil sample collected from the Arctic. Strain 1E403 was Gram-stain-negative, yellow-pigmented, rod-shaped, gliding and aerobic. Growth occurred at 4-37 °C (optimum, 28 °C), pH 6.0-9.0 (pH 7.0) and with 0-2 % (w/v) NaCl (0 %) on modified marine agar 2216. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that strain 1E403 was affiliated with the genus and was more closely related to DSM 21790 (96.6 %) than to other species. genomic comparisons, including average nucleotide identity and the digital DNA-DNA hybridization values, showed 73.9 % and 18.8 % identity to the closest relative DSM 21790, respectively. The average amino acid identity value between strain 1E403 and DSM 1132 was 63.8 %. The DNA G+C content of the strain was 36.8 %, while the sole respiratory quinone was menaquinone-6. Iso-C and summed feature 3 (Cω7 and/or Cω6) were the major fatty acids (>10 %) of strain 1E403. The polar lipid profile of strain 1E403 contained phosphatidylethanolamine, four unidentified aminolipids and two unidentified phospholipids. Based on the phenotypic characteristics, chemotaxonomic characteristics and phylogenetic inference, strain 1E403 represents a novel species of the genus , and we propose the name sp. nov. The type strain of sp. nov. is 1E403 (=KCTC 62960=MCCC 1H00356).
