title: Endozoicomonas atrinae sp. nov., isolated from the intestine of a comb pen shell Atrina pectinata.
abstract: A novel bacterium, designated strain WP70(T), was isolated from the gut of a comb pen shell (Atrina pectinata) collected from the southern sea of Yeosu in Korea. The isolate was Gram-stain-negative, aerobic, non-motile and rod-shaped. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain WP70(T) belonged to the genus Endozoicomonas. The highest level of sequence similarity (98.4%) was shared with Endozoicomonas elysicola MKT110(T). Optimal growth occurred in 2% (w/v) NaCl at 30 °C and at pH 7. The major cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c) and C16 : 0. The main respiratory quinone was Q-9. The polar lipids comprised phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol, three unidentified phospholipids, an unidentified aminolipid, an unidentified aminophospholipid and an unidentified lipid. The genomic DNA G+C content was 50.5 mol% and DNA-DNA hybridization values indicated <11% genomic relatedness to the closest species. Physiological, biochemical, chemotaxonomic and genotypic analyses indicated that strain WP70(T) represents a novel species of the genus Endozoicomonas, for which the name Endozoicomonas atrinae sp. nov. is proposed. The type strain is WP70(T) ( = KACC 17474(T)  = JCM 19190(T)).
