Abstract

A Gram-negative, motile, rod-shaped bacterial strain, designated Ad2, was isolated from a marine sponge, , which was collected from a semi-enclosed marine lake in Ireland. Strain Ad2 grew optimally at 24 °C, at pH 7.0 and in the presence of 3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain Ad2 clustered with members of the genus , and showed 97.3–98.2 % sequence similarity to the type strains of recognized species. DNA–DNA relatedness values between strain Ad2 and the type strains of other species were <27 %. The DNA G+C content of strain Ad2 was 50.5 mol%. The major fatty acid was 18 : 1ω7. Differences in phenotypic properties, together with phylogenetic and DNA–DNA hybridization analyses, indicated that strain Ad2 represented a novel species of the genus . The name sp. nov. is proposed, with Ad2 ( = DSM 24994 = NCIMB 14761) as the type strain.
