Abstract

The taxonomic position of a novel marine, heterotrophic, gliding, halotolerant and light-pink-pigmented bacterium, designated strain KMM 6221T, was examined by using a polyphasic approach. 16S rRNA gene sequence analysis indicated that strain KMM 6221Tis affiliated with the genusEchinicola, a member of the phylumBacteroidetes, with levels of similarity of 94.7–95.0 % to strains ofEchinicola pacifica. Growth of strain KMM 6221Twas observed with 0–15 % NaCl and at 6–44 °C. The DNA G+C content of strain KMM 6221Twas 45.9 mol%. On the basis of molecular distinctiveness supported by phenotypic and chemotaxonomic data, strain KMM 6221Tis considered to represent a novel species of the genusEchinicola, for which the nameEchinicola vietnamensissp. nov. is proposed. The type strain is KMM 6221T(=DSM 17526T=LMG 23754T).
