Abstract

A Gram-stain-negative, non-flagellated, non-gliding and rod-shaped bacterial strain, designated TM-6, was isolated from a tidal flat sediment in the Korean peninsula. Strain TM-6 was found to grow optimally at pH 7.0–8.0, at 30 °C and in the presence of 2–3% (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain TM-6 joined the clade comprising recognized species of the genus , with which it exhibited 94.7– 95.2 % sequence similarity. Strain TM-6 was found to contain iso-C, iso-C G and iso-C 3-OH as major fatty acids. The only isoprenoid quinone was menaquinone-7 (MK-7). The major polar lipids were identified as phosphatidylethanolamine and three unidentified lipids. The DNA G+C content of strain TM-6 was 50.9 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, revealed that strain TM-6 is distinguishable from recognized species. On the basis of the data presented, strain TM-6 is proposed to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is TM-6 (=KCTC 42720=CECT 9024).
