ABSTRACT
A Gram-reaction-negative, aerobic, flagellated and coccoid-shaped bacterial strain, designated SM1702T, was isolated from Antarctic intertidal sediment collected off Ardely Island, West Antarctica. The strain grew at 0-30 °C and with 0.5-5.0â% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences and single-copy orthologous clusters both showed that strain SM1702T, together with Poseidonibacter lekithochrous, occupied an independent phylogenetic branch, sharing the highest 16S rRNA gene sequence similarity with type strain of the latter (95.6â%). The major fatty acids were summed feature 3 (C16ââ1 ω7c and/or C16ââ1 ω6c), summed feature 8 (C18ââ1 ω7c and/or C18ââ1 ω6c), C16ââ0, and summed feature 2 (C14ââ0 3-OH and/or iso-C16ââ1 I). Polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA G+C content of strain SM1702T was 27.1 mol%. Based on the results of the polyphasic characterisation for strain SM1702T, it is identified as the representative of a novel species of Poseidonibacter, for which the name Poseidonibacter antarcticus sp. nov. is proposed. The type strain of Poseidonibacter antarcticus is SM1702T (=MCCC 1K03471T=KCTC 62796T).
