Abstract

A Gram-reaction-negative, aerobic, flagellated and coccoid-shaped bacterial strain, designated SM1702, was isolated from Antarctic intertidal sediment collected off Ardely Island, West Antarctica. The strain grew at 0–30 °C and with 0.5–5.0 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences and single-copy orthologous clusters both showed that strain SM1702, together with , occupied an independent phylogenetic branch, sharing the highest 16S rRNA gene sequence similarity with type strain of the latter (95.6 %). The major fatty acids were summed feature 3 (C 7 and/or C 6), summed feature 8 (C 7 and/or C 6), C, and summed feature 2 (C 3-OH and/or iso-C I). Polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA G+C content of strain SM1702 was 27.1 mol%. Based on the results of the polyphasic characterisation for strain SM1702, it is identified as the representative of a novel species of , for which the name sp. nov. is proposed. The type strain of is SM1702 (=MCCC 1K03471=KCTC 62796).
