Abstract

A Gram-stain-negative, rod-shaped, non-motile, strictly aerobic, chemoheterotrophic, pale-yellow-pigmented bacterium, designated strain A6D-50, was isolated from an ascidian collected at Kohama Island offshore Okinawa, Japan. Preliminary analysis based on the 16S rRNA gene sequence revealed that the novel isolate was affiliated with the family of the phylum and that it showed highest sequence similarity (97.6 %) to 04OKA003-7. The DNA–DNA relatedness value between strain A6D-50 and 04OKA003-7 was 23.6 %. The DNA G+C content of strain A6D-50 was 40.8 mol%, MK-6 was the only menaquinone, and iso-C 3-OH, iso-C, iso-C G and summed feature 3 (C 7 and/or C 6) were the major (>10 %) cellular fatty acids. The polar lipid profile consisted of phosphatidylethanolamine, two unidentified aminolipids and an unidentified lipid. From the distinct phylogenetic position and combination of genotypic and phenotypic characteristics, the strain is considered to represent a novel species of the genus for which the name sp. nov. is proposed. The type strain is A6D-50 (= KCTC 42975=NBRC 111827).
