Strain KUDC5002 was isolated from soil sampled on the Dokdo Islands, Republic of Korea. This bacterial strain was Gram stain-positive, non-motile, rod-shaped, capable of growing at 25-37°C and pH 5.0-12.0, and showed optimal growth at 30 °C and pH 7.0-8.0. Strain KUDC5002 could be grown in tryptic soy broth containing less than 7.0 % NaCl (w/v). The cell width ranged from 0.5 to 0.6 µm and length ranged from 0.8 to 1.0 µm. Strain KUDC5002 was catalase- and oxidase-positive. Its genomic G+C content was 72.2 mol%. Its major fatty acids were C 9 (17.3 %), iso-C (16.0 %) and iso-C (11.4 %). Phylogenetic analysis, based on 16S rRNA gene sequences, showed that strain KUDC5002 belongs to the genus and is most closely related to strain DCY24 (97.0 %). Based on its phenotypic, phylogenetic, genetic and chemotaxonomic features, strain KUDC5002 should be considered a novel species in the genus , for which we have proposed the name sp. nov. The type strain is KUDC5002 (=KCTC 39855=DSM 106604).
菌株 KUDC5002 是从韩国独岛土壤中分离出来的。该细菌为革兰氏阳性、非运动性、杆状，能在 25-37°C 和 pH5.0-12.0 下生长，最适生长温度为 30°C，最适 pH 为 7.0-8.0。KUDC5002 菌株能在含少于 7.0%（w/v）NaCl 的胰蛋白胨大豆肉汤中生长。细胞宽度为 0.5-0.6μm，长度为 0.8-1.0μm。KUDC5002 菌株过氧化氢酶和氧化酶阳性。其基因组 G+C 含量为 72.2mol%。其主要脂肪酸为 C9（17.3%）、iso-C（16.0%）和 iso-C（11.4%）。基于 16S rRNA 基因序列的系统发育分析表明，菌株 KUDC5002 属于 属，与菌株 DCY24（97.0%）最为密切相关。基于其表型、系统发育、遗传和化学分类特征，菌株 KUDC5002 应被视为 属的一个新种，我们建议将其命名为 sp. nov.。模式菌株为 KUDC5002（=KCTC 39855=DSM 106604）。
