A Gram-positive, aerobic, non-motile and coccoid actinobacterium, designated P31(T), was isolated from a traditional, fermented seafood. The strain was catalase-positive and oxidase-negative. Cells grew in the presence of 0-15.0 % (w/v) NaCl, and at pH 5-10 and 15-37 degrees C. Major cellular fatty acids were anteiso-C(15 : 0), anteiso-C(17 : 0) and iso-C(16 : 0). Strain P31(T) contained MK-7 as the predominant menaquinone. The DNA G+C content of the genomic DNA of strain P31(T) was 65.2 mol%. A phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain P31(T) was most closely related to Kocuria kristinae DSM 20032(T), with 96.9 % similarity, and these two strains clustered together in constructed phylogenetic trees. The DNA-DNA hybridization value between strain P31(T) and K. kristinae DSM 20032(T) was 21.1 %. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, it is suggested that strain P31(T) represents a novel species of the genus Kocuria, for which the name Kocuria koreensis sp. nov. is proposed. The type strain is P31(T) (=KCTC 19595(T)=JCM 15915(T)).
一株革兰氏阳性、需氧、非运动和球形放线菌,命名为 P31(T),从传统的发酵海鲜中分离得到。该菌株过氧化氢酶阳性,氧化酶阴性。细胞在 0-15.0%(w/v)NaCl、pH5-10 和 15-37°C 的条件下生长。主要细胞脂肪酸为anteiso-C(15:0)、anteiso-C(17:0)和 iso-C(16:0)。菌株 P31(T)含有 MK-7 作为主要的menaquinone。菌株 P31(T)的基因组 DNA 的 G+C 含量为 65.2mol%。基于 16S rRNA 基因序列的系统发育分析表明,菌株 P31(T)与 Kocuria kristinae DSM 20032(T)最为密切相关,相似度为 96.9%,这两个菌株在构建的系统发育树中聚在一起。菌株 P31(T)与 K. kristinae DSM 20032(T)之间的 DNA-DNA 杂交值为 21.1%。基于表型、化学分类和系统发育数据,建议菌株 P31(T)代表 Kocuria 属的一个新种,命名为 Kocuria koreensis sp. nov.。模式菌株为 P31(T)=KCTC 19595(T)=JCM 15915(T)。
