sp. nov., isolated from a tidal flat Free

Abstract

A Gram-stain-negative, non-motile, aerobic and coccoid or rod-shaped bacterium, designated GHTF-23, was isolated from a tidal flat of the South Sea, South Korea. GHTF-23 grew optimally at 37 °C, at pH 6.5–7.5 and in the presence of 2.0 % (w/v) NaCl. In the neighbour-joining phylogenetic tree based on 16S rRNA gene sequences, GHTF-23 fell within the clade comprising the type strains of species of the genus . GHTF-23 exhibited 16S rRNA gene sequence similarities of 97.1–97.9 % to the type strains of , , , and and 94.5–96.8 % to the type strains of the other species of the genus . GHTF-23 contained Q-8 as the predominant ubiquinone and iso-C and summed feature 3 (Cω7 and/or Cω6) as the major fatty acids. The major polar lipids detected in GHTF-23 and DSM 11525 were phosphatidylethanolamine, phosphatidylglycerol and one unidentified glycolipid. The DNA G+C content of GHTF-23 was 60.1 mol% and its mean DNA–DNA relatedness values with the type strains of , , , and were 11–31 %. The differential phenotypic properties, together with the phylogenetic and genetic distinctiveness, revealed that GHTF-23 is separated from species of the genus with validly published names. On the basis of the data presented, GHTF-23 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is GHTF-23 (=KCTC 52569=NBRC 112533).
