Abstract

A Gram-stain-negative, strictly aerobic and moderately halophilic bacterial strain, designated strain PoM-212, was isolated from a marine alga, , in the Republic of Korea. Cells were catalase- and oxidase-positive rods with gliding motility without flagellum. Growth was observed at 20–40 °C (optimum, 30 °C) and pH 5.0–8.5 (pH 5.0–5.5) and in the presence of 0.5–5 % (w/v) NaCl (2–3 %). Strain PoM-212 contained iso-C, iso-C, iso-C 3-OH and summed feature 3 (comprising Cω7 and/or Cω6) as major fatty acids and menaquinone-6 as the sole isoprenoid quinone. Phosphatidylethanolamine, three unidentified aminolipids and two unidentified polar lipids were detected as major polar lipids. The G+C content of the genomic DNA was 41.0 mol%. Strain PoM-212 was most closely related to KJ4, CDA4 and C3 with 97.2, 97.2 and 97.0 % 16S rRNA gene sequence similarities, respectively, and it formed a distinct phylogenetic lineage from them within the genus . formed a close phylogenetic lineage with with 99.7 % 16S rRNA gene sequence similarity, but their digital DNA–DNA hybridization value was 67.4 %. On the basis of its phenotypic, chemotaxonomic and molecular properties, strain PoM-212 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is PoM-212 (=KACC 19789=JCM 32941). The transfer of to the genus as comb. nov. is also proposed (type strain CDA4=KCTC 52409=MCCC 1K03210).
