A polyphasic taxonomic approach was used to characterize a Gram-stain-positive bacterium, designated strain CC-CFT480, isolated from soil sampled in a maize field in Taiwan, ROC. Cells of strain CC-CFT480 were rod-shaped, motile with polar flagella, catalase-positive and oxidase-positive. Optimal growth occurred at 30 °С, pH 8 and 3 % NaCl. Phylogenetic analyses based on 16S rRNA genes revealed a distinct taxonomic position attained by strain CC-CFT480 associated with (97.2 % sequence identity), (95.7 %), (95.4 %) and (95.2 %), and lower sequence similarity values to other species. Average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between strain CC-CFT480 and were 74.2 and 20.1 %, respectively. Strain CC-CFT480 contained iso-C, C c alcohol and iso-C 10 as the predominant fatty acids. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, two unknown aminophospholipids, one uncharacterized aminophospholipid and two unknown phospholipids. The major polyamine was spermidine. The DNA G+C content was 34.8 mol% and the predominant quinone was menaquinone 7 (MK-7). Based on its distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence, ANI and dDDH analyses, strain CC-CFT480 is proposed to represent a novel species, for which the name sp. nov. (type strain CC-CFT480=BCRC 81216=JCM 33498).
采用多相分类法对一株革兰氏阳性菌进行了研究,该菌被命名为 CC-CFT480 株,从中国台湾省玉米地土壤中分离得到。CC-CFT480 株的细胞呈杆状,有极生鞭毛,可运动,接触酶和氧化酶均为阳性。最适生长温度为 30°C,pH 值为 8,NaCl 浓度为 3%。基于 16S rRNA 基因的系统发育分析表明,CC-CFT480 株与 (97.2%序列同一性)、 (95.7%)、 (95.4%)和 (95.2%)密切相关,与其他种的序列相似性较低。CC-CFT480 株与 之间的平均核苷酸同一性(ANI)和数字 DNA-DNA 杂交(dDDH)值分别为 74.2%和 20.1%。CC-CFT480 株含有 iso-C 15:0、C c 醇和 iso-C 10 为主要脂肪酸。极性脂谱由二磷脂酰甘油、磷脂酰乙醇胺、磷脂酰甘油、两种未知的氨基磷脂、一种未鉴定的氨基磷脂和两种未知的磷脂组成。主要聚胺为亚精胺。DNA G+C 含量为 34.8 mol%,主要醌为menaquinone 7(MK-7)。基于其独特的系统发育、表型和化学分类特征以及比较 16S rRNA 基因序列、ANI 和 dDDH 分析的结果,CC-CFT480 株被提议代表一个新的 种,命名为 sp. nov.(模式菌株 CC-CFT480=BCRC 81216=JCM 33498)。
