Abstract

A marine bacterium, named strain feces2, was isolated from the excreted faeces of an abalone, . The bacterium was Gram-stain-negative, rod-shaped and had a polar flagellum. It formed a white, small and crater-like colony on an agar plate, and had the capability of degrading agar. Activity of oxidase was positive and that of catalase was negative. Strain feces2 grew at 16 to 40 °C with an optimum of 28–30 °C. The nearly full-length 16S rRNA gene of strain feces2 had the greatest sequence similarity of 92.9 % with Q-192, followed by of 92.8 % with T7902. Phylogenetic analysis indicated that strain feces2 belonged to the family , representing an independent clade with an uncultured bacterium clone NEP3-15 (98 % sequence similarity of 16S rRNA gene) derived from the phycosphere of . The respiratory quinone was ubiquinone Q-8. The predominant fatty acids consisted of summed feature 8 (C 7/C 6), C and summed feature 3 (C 6/C ω). The polar lipids were identified as phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, an unidentified amino phospholipid and four unknown lipids. The genomic DNA G+C content was 50.5 mol%. On the basis of polyphasic characterizations, strain feces2 represented a novel species and a novel genus in the family of the order within the , for which the name gen. nov., sp. nov. is proposed, with the type strain being feces2 (=MCCC 1A11450=KCTC 52708).
