Abstract

A Gram-positive, non-motile and rod- or coccoid-shaped bacterial strain, MDN22, was isolated from a soil sample from Korea. Strain MDN22 grew optimally at pH 7.0–8.0, at 30 °C and in the presence of 0–0.5 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain MDN22 was phylogenetically most closely related to the genera and . In the neighbour-joining phylogenetic tree, strain MDN22 was most closely related to KCTC 9134, with which it exhibited 98.3 % 16S rRNA gene sequence similarity. The strain exhibited 93.1–96.9 % and 95.3–95.9 % 16S rRNA gene sequence similarities to the type strains of other species of the genera and , respectively. The chemotaxonomic properties of strain MDN22 were consistent with those of the genus ; the cell-wall peptidoglycan type was based on -2,6-diaminopimelic acid, the predominant menaquinone was MK-8(H) and the major fatty acids were iso-C and C. The DNA G+C content was 68.7 mol%. DNA–DNA relatedness data and differential phenotypic properties suggested that strain MDN22 could be differentiated from and . On the basis of the data obtained, strain MDN22 is considered to represent a novel species of the genus , for which the name sp. nov., is proposed. The type strain is MDN22 (=KCTC 19601=CCUG 57505).
