Abstract

A Gram-negative, rod-shaped bacterium (designated strain UST030701-295) with fast gliding motility was isolated from the surface of the sponge in the Bahamas. Colonies of UST030701-295 were yellow in colour, 2–4 mm in diameter, convex with a smooth surface and entire margins. UST030701-295 was heterotrophic, strictly aerobic and required NaCl for growth (1·0–4·0 %). Growth was observed at pH 6·0–10·0 and at 12–44 °C. Phylogenetic analysis of the 16S rRNA gene sequence placed UST030701-295 within the genus of the family , sharing 94·7–95·8 % similarity with the three recognized members of the genus. The G+C content of the DNA was 32·8 mol% and the predominant fatty acids were iso-C, iso-C, iso-C 2-OH, iso-C 3-OH, iso-C 3-OH, C 7 and iso-C 3-OH (together representing 75·4 % of the total); these data supported the affiliation of UST030701-295 to the genus . UST030701-295 differed from the three recognized species of in 7–17 traits. Molecular evidence together with phenotypic characteristics suggests that UST030701-295 represents a novel species within the genus , for which the name sp. nov. is proposed. The type strain is UST030701-295 (=NRRL B-41101=JCM 12885).
