| Abstract |
A novel bacterial isolate, designated as strain BM15T, was isolated from the gastrointestinal tract of a blood cockle, Tegillarca granosa, which was collected from the foreshore of Beolgyo-eup, Republic of Korea. Strain BM15T was Gram-stain-negative, non-motile, strictly aerobic and short-rod-shaped. Optimum growth of the isolate occurred at 20 °C, in the presence of 4 % (w/v) NaCl and at pH 6. The 16S rRNA gene sequence analysis showed that strain BM15T belonged to the genus Paracoccus and had more than 97 % 16S rRNA gene sequence similarity to 'Paracoccus zhejiangensis' J6 (97.40 % similarity) and Paracoccus lutimaris HDM-25T (97.04 %). The polar lipid profile of strain BM15T comprised phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, an unidentified glycolipid and two unidentified lipids. The predominant respiratory quinone was ubiquinone-10. The major cellular fatty acid (>20 %) was summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). The complete genome sequence of strain BM15T comprised 3,759,866 bp with 62.2 mol% G+C content. The results of the phylogenetic, phenotypic and genotypic analyses indicated that strain BM15T represents a novel species in the genus Paracoccus, for which the name Paracoccus tegillarcae is proposed. The type strain is BM15T (=KCTC 72032T=JCM 33289T).
