Abstract

A Gram-negative, motile, non-spore-forming, rod-shaped strain, TF-27 (=KCCM 41648=JCM 11814), was isolated from a tidal flat in Korea. This organism grew well at 25–35 °C, with optimum growth at 30 °C. Strain TF-27 grew optimally in the presence of 2 % NaCl; it did not grow without NaCl or in the presence of >8 % NaCl. Strain TF-27 simultaneously contained both menaquinones and ubiquinones as isoprenoid quinones. The predominant menaquinone was MK-7 and the predominant ubiquinones were Q-7 and Q-8. The major fatty acids in strain TF-27 were iso-C (20·6 %) and iso-C 2-OH and/or C 7 (21·1 %). The DNA G+C content of strain TF-27 was 42 mol%. Phylogenetic analyses based on 16S rDNA sequences showed that strain TF-27 falls within the radiation of the cluster that is encompassed by the genus . Levels of 16S rDNA sequence similarity between strain TF-27 and the type strains of species were 93·2–96·8 %. On the basis of phenotypic properties and phylogenetic data, strain TF-27 should be placed in the genus as a novel species, for which the name sp. nov. is proposed.
