A Gram-stain-positive, rod-shaped, aerobic, endospore-forming bacterium, designated strain N2SHLJ1, was isolated from a surface-sterilized tissue sample of L. in Guizhou, PR China. To determine the bacterium's taxonomic position, it was characterized by a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequencing suggested that strain N2SHLJ1 belongs to the genus and is most closely to CJ25 (94.7 % similarity). Strain N2SHLJ1 grew at 10-37 °C (optimum, 30 °C), in 0-2 % (w/v) NaCl (optimum, 0 %) and in pH 5.0-8.0 (optimum, 7.0). The cell-wall peptidoglycan contained -diaminopimelic acid and the predominant menaquinone was MK-7. The major fatty acids were anteiso-C and iso-C. The polar lipids comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, an unidentified aminophospholipid, an unidentified phospholipid, an unidentified aminolipid, an unidentified glycolipid and two unidentified lipids. The DNA G+C content was 50.8 mol%. Based on the results of phylogenetic, phenotypic and chemotaxonomic analysis, strain N2SHLJ1 was clearly distinguished from other species with validly published names in the genus and should therefore be designated as a novel species, for which the name sp. nov. is proposed. The type strain is N2SHLJ1 (=JCM 33293=CGMCC 1.13865).
一株革兰氏阳性、杆状、需氧、产芽孢的细菌,被命名为 N2SHLJ1 菌株,从中国贵州的一个表面消毒组织样本中分离得到。为了确定该细菌的分类地位,采用多相分类法对其进行了表征。基于 16S rRNA 基因测序的系统发育分析表明,菌株 N2SHLJ1 属于 属,与 CJ25 最为密切(相似度为 94.7%)。N2SHLJ1 菌株在 10-37°C(最佳温度为 30°C)、0-2%(w/v)NaCl(最佳浓度为 0%)和 pH 5.0-8.0(最佳 pH 值为 7.0)的条件下生长。细胞壁肽聚糖含有 -二氨基庚二酸,主要的menaquinone 是 MK-7。主要脂肪酸为 anteiso-C 和 iso-C。极性脂包括双磷脂酰甘油、磷脂酰甘油、磷脂单甲醚乙醇胺、磷脂乙醇胺、一种未鉴定的氨基磷脂、一种未鉴定的磷脂、一种未鉴定的氨基脂、一种未鉴定的糖脂和两种未鉴定的脂类。DNA G+C 含量为 50.8mol%。基于系统发育、表型和化学分类学分析的结果,菌株 N2SHLJ1 与属内其他具有有效发表名称的种明显不同,因此应被指定为一个新种,建议将其命名为 sp. nov. 。其模式菌株是 N2SHLJ1(=JCM 33293=CGMCC 1.13865)。
