A Gram-positive-staining, facultatively anaerobic bacterial strain, CTT-37, was isolated from a marine sediment sample collected from Tottori city, located on the shore of the Sea of Japan. A 16S rRNA gene sequence comparison indicated that the isolate represents a novel clade that clusters with members of the families and . Strain CTT-37 shared maximum 16S rRNA gene sequence similarity of 96.4 % with DSM 14281 and 96.2 % with DSM 43852. The DNA–DNA hybridization value between strain CTT-37 and JCM 7350 was 10–12 %. The following chemotaxonomic characteristics of strain CTT-37 were markedly different from those of strains in the genus . The cell wall contained -serine in the peptidoglycan interpeptide bridge. The predominant menaquinone was MK-9 (H); other quinones detected were MK-9 and MK-9(H). The only polar lipid was phosphatidylglycerol and the G+C content of the DNA was 70 mol%. Differences in phenotypic characteristics and large phylogenetic distances between strain CTT-37 and all members of the genus supported the classification of CTT-37 within a new genus and species, for which the name gen. nov., sp. nov. is proposed. The type strain of is CTT-37 (=NBRC 104352 =DSM 21750).
