Abstract

A bacterial strain, designated CL-22, was isolated from an encrusting pore coral, , collected off the coast of Southern Taiwan. Its taxonomic position was investigated using a polyphasic approach. Cells of strain CL-22 were Gram-stain-negative, aerobic, motile by means of a single polar flagellum, rod-shaped and formed yellow colonies. Optimal growth occurred at 30 °C, pH 6.5−7 and in 2 % (w/v) NaCl. A neighbour-joining phylogenetic tree, based on 16S rRNA gene sequences, showed that strain CL-22 fell into the clade comprising the type strains of species of the genus . Strain CL-22 exhibited 16S rRNA gene sequence similarity values of 94.7–97.1 % to the type strains of species of the genus . The major fatty acids (>10 %) of strain CL-22 were summed feature 3 (Cω7 and/or Cω6) and C. The predominant isoprenoid quinone was Q-8. The major polar lipids were phosphatidylethanolamine and phosphatidylglycerol. The genomic DNA G+C content of strain CL-22 was 41.2 mol%. The differential phenotypic properties, together with the phylogenetic inference, demonstrate that strain CL-22 should be classified as a novel species of the genus ; the name sp. nov. is proposed. The type strain is CL-22 (=LMG 24827=BCRC 17940).
