Abstract

A Gram-negative, non-spore-forming, non-motile rod, designated MA-My1, was isolated from a tidal flat sediment of the South Sea, Korea. Strain MA-My1 grew optimally at pH 7.0–7.5, at 30 °C and with 2.0–3.0 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain MA-My1 clustered with CL-TF09 and S7-2, with which it exhibited 97.3 and 95.3 % 16S rRNA gene sequence similarity, respectively. Strain MA-My1 contained MK-6 as the predominant menaquinone and iso-C, iso-C 3-OH and iso-C 3-OH as the major fatty acids. The major polar lipids were phosphatidylethanolamine and two unidentified lipids. The DNA G+C content was 30.6 mol% and DNA–DNA relatedness between strain MA-My1 and JCM 13034 was 6.3±0.8 %. The differential phenotypic properties, together with phylogenetic and genotypic distinctiveness, distinguished strain MA-My1 from the members of the genus . On the basis of the data presented, strain MA-My1 is considered to represent a novel species of the genus for which the name sp. nov. is proposed. The type strain is MA-My1 ( = KCTC 23499  = CCUG 60022).
