Abstract
- A Gram-stain-negative, rod-shaped and non-motile strain, designated PAMC 27266T, was isolated from deep-sea sediment of the Arctic Ocean. Analysis of the 16S rRNA gene sequence of strain PAMC 27266T showed closest affiliation with the genus Sediminicola . Phylogenetic analyses revealed that strain PAMC 27266T formed a robust clade with Sediminicola luteus CNI-3T, with which it shared 98.9 % 16S rRNA gene sequence similarity. Genomic relatedness analyses based on the average nucleotide identity and genome-to-genome distance showed that strain PAMC 27266T is clearly distinguished from S. luteus . Cells of strain PAMC 27266T grew optimally at 15 °C and pH 6.5–7.5 in the presence of 3.5 % (w/v) sea salts. The major polar lipids were phosphatidylethanolamine, two unidentified aminophospholipids and two unidentified lipids. The only respiratory quinone was menaquinone-6. The major cellular fatty acids (>10 %) were C16 : 1ω6c and/or C16 : 1ω7c and C15 : 0. The genomic DNA G+C content was 37.9 mol%. Based on the phylogenetic, genomic, chemotaxonomic and phenotypic data presented, we propose strain PAMC 27266T ( = KCCM 43038T = JCM 19894T) as the type strain of a novel species, with the name Sediminicola arcticus sp. nov.
