A novel Gram-positive, aerobic, short-rod-shaped bacterium, designated strain J112, was isolated from black sand collected from Soesoggak, Jeju Island, Korea. The strain was found to be oxidase-negative and catalase-positive. Cells grew at 10–37 °C, at pH 5.5–8.0 and with 1–10 % NaCl. Growth occurred on marine agar but not on R2A or trypticase soy agar. A phylogenetic analysis based on 16S rRNA gene sequences showed that the strain belongs to the radiation of the genus . Strain J112 shared the highest 16S rRNA gene sequence similarities with SBS-12 (99.2 %), DS-17 (97.3 %), KCTC 19038 (97.1 %) and type strains of other species with validly published names (<97 %). The DNA–DNA hybridization values between strain J112 and the three most closely related strains were low enough to justify the assignment of this strain to a novel species. On the basis of these phenotypic, phylogenetic and chemotaxonomic data, strain J112 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is J112 (=KCTC 19365=JCM 14945).
