Abstract

A novel Gram-staining-negative, aerobic, non-motile, yellow-to-orange carotenoid-type-pigmented and rod-shaped bacterium, designated strain WP25, was isolated from the intestine of a comb pen shell, , which was collected from the South Sea near Yeosu in Korea. The isolate grew optimally at 20 °C, at pH 7 and with 2 % (w/v) NaCl. 16S rRNA gene sequence analysis showed that strain WP25 belonged to the genus in the family and the highest sequence similarity was shared with the type strain of (98.5 %). The major cellular fatty acids were iso-C, anteiso-C, Cω6 and iso-C 3-OH. The main respiratory quinone was menaquinone MK-6. The polar lipids of strain WP25 were phosphatidylethanolamine, two unidentified aminolipids, an unidentified phospholipid and four unidentified lipids. The genomic DNA G+C content was 31.2 mol%. DNA–DNA hybridization experiments indicated <12.6 % genomic relatedness with closely related strains. Based on phylogenetic, phenotypic and genotypic analyses, strain WP25 represents a novel species in the genus , for which the name sp. nov. is proposed, with the type strain WP25 ( = KACC 17473 = JCM 19202).
