Abstract

A bacterial strain, designated SW6, was isolated from the reef-building coral , collected from seawater off the coast of southern Taiwan, and characterized using a polyphasic taxonomic approach. Strain SW6 was Gram-negative, aerobic, beige coloured, rod-shaped and motile by monopolar flagella. 16S rRNA gene sequence studies showed that the strain clustered closely with JCM 13038 (97.9 % 16S rRNA gene sequence similarity). Strain SW6 required NaCl for growth and exhibited optimal growth at 25–30 °C and 3–4 % NaCl. The predominant cellular fatty acid was summed feature 8 (Cω7/Cω6; 64.1 %). The major respiratory quinone was ubiquinone Q-10 and the DNA G+C content was 54.9 mol%. The results of physiological and biochemical tests allowed clear phenotypic differentiation of this isolate from previously described species of the genus . It is evident from the genotypic, phenotypic and chemotaxonomic data that the new strain should be classified as a representative of a novel species in the genus . The name proposed for this taxon is sp. nov.; the type strain is SW6 ( = LMG 25377 = BCRC 80085).
