Paracoccus tegillarcae sp. nov., isolated from the gastrointestinal tract of a blood cockle (Tegillarca granosa)

A novel bacterial isolate, designated as strain BM15 T , 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 BM15 T 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 BM15 T 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-25 T (97.04 %). The polar lipid profile of strain BM15 T 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 (C 18 : 1 ω 7 c and/or C 18 : 1 ω 6 c ). The complete genome sequence of strain BM15 T comprised 3,759,866 bp with 62.2 mol% G+C content. The results of the phylogenetic, phenotypic and genotypic analyses indicated that strain BM15 T represents a novel species in the genus Paracoccus , for which the name Paracoccus tegillarcae is proposed. The type strain is BM15 T (=KCTC 72032 T =JCM 33289 T ).
