sp. nov., isolated from subarctic rainwater Free

Abstract

A Gram-stain-positive, rod-shaped and non-motile strain, designated PAMC 27367, was isolated from rainwater collected on the Bering Sea. Analysis of the 16S rRNA gene sequence of the strain showed an affiliation with the genus . Phylogenetic analyses revealed that strain PAMC 27367 formed a robust clade with the type strains of , and with 16S rRNA gene sequence similarities of 96.3 %, 95.8 % and 95.5 %, respectively. Cells of the strain grew optimally at 25 °C and at pH 6.5–7.0 in the presence of 0–2 % (w/v) sea salts. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside and three unknown phospholipids. The major cellular fatty acids (>10 %) were iso-C, Cω8 and 10-methyl C. Cell wall analysis showed that strain PAMC 27367 contained -diaminopimelic acid. The genomic DNA G+C content was 77.1 mol%. Based on the phylogenetic, chemotaxonomic and phenotypic data presented here, we propose a novel species with the name sp. nov., with PAMC 27367 ( = KCTC 29240 = JCM 19485) as the type strain.
