gen. nov., sp. nov., a lipolytic bacterium isolated from a tidal flat Free

Abstract

A Gram-stain-negative, flagellated, aerobic and rod-shaped or ovoid bacterial strain, designated HJTF-7, was isolated from a tidal flat on the South Sea of South Korea, and its taxonomic position was investigated using a polyphasic approach. Strain HJTF-7 grew optimally at 25 °C, at pH 7.0–8.0 and in the presence of 2.0 % (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees, based on 16S rRNA gene sequences, showed that strain HJTF-7 joined the cluster comprising the type strains of species of the genera and . Strain HJTF-7 exhibited 16S rRNA gene sequence similarities of 90.4–92.5 % to the type strains of species of the genera and and of less than 91.5 % to the type strains of other recognized species. Strain HJTF-7 contained Q-8 as the predominant ubiquinone. The major fatty acids were iso-Cω9, iso-C, iso-C, iso-C 3-OH and Cω8 and the major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The fatty acid and polar lipid profiles of strain HJTF-7 were distinct from those of members of the genera and . The DNA G+C content of strain HJTF-7 was 55.9 mol%. The phylogenetic data and differential chemotaxonomic and other phenotypic properties revealed that strain HJTF-7 represents a novel genus and species within the class , for which the name gen. nov., sp. nov. is proposed. The type strain of is HJTF-7 ( = KCTC 42157 = CECT 8654).
