Abstract

A novel Gram-stain-negative, coccus-shaped, aerobic and motile bacterial strain, designated S12M18, was isolated from the gut of the Korean turban shell, . Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S12M18 belonged to the genus and had the highest 16S rRNA gene sequence similarity twith HDW-19 (98.63 %). The phylogenomic tree congruently verified that strain S12M18 occupies a taxonomic position within the genus . The OrthoANIu value between strain S12M18 and HDW-19 was 87.22 %. The major cellular fatty acid of strain S12M18 was summed feature 8 (C ω7 or C ω6). The major components of the polar lipids were phosphatidylcholine, phosphatidylglycerol and phosphatidylethanolamine. The predominant isoprenoid quinone was Q-10. The DNA G+C content was 57.8 mol%. The polyphasic analyses indicated that strain S12M18 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is S12M18 (=KCTC 62742=JCM 33168).
