A Gram-stain-positive, aerobic, rod-shaped, and non-motile bacterium, designated strain R7T, was isolated from pig faeces. Strain R7T grew at 15-37 °C (optimum 30 °C), pH 6-8 (optimum pH 7), and salinity of 0-5.0% (w/v; optimum 1.0%). Strain R7T was resistant to cefradine, ampicillin, gentamicin, and spectinomycin. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain R7T belonged to genus Oryzobacter, and showed 98.9% similarity w... ...点击完成人机验证后继续浏览

一种从猪粪便中分离出来的革兰氏阳性、需氧、杆状且非运动的细菌菌株R7^T被鉴定。菌株R7^T在15-37℃（最适温度30℃）、pH 6-8（最适pH值为7）以及0-5.0%（w/v；最适盐分为1.0%）的条件下生长。该菌株对头孢雷丁、氨苄青霉素、庆大霉素和新霉素耐药。基于16S rRNA基因序列进行的系统发育分析表明，菌株R7^T属于稻杆菌属（Oryzobacter），与模式菌株稻杆菌土型PSGM2-16^T的相似度为98.9%。菌株R7^T和O. terrae PSGM2-16^T之间的平均核苷酸同一性和数字DNA-DNA杂交值分别为84.5%和27.6%。菌株R7^T的主要脂肪酸为异构C_16:0、C_17:1ω8c、异构C_14:0、C_17:0和异构C_15:0。主要泛醌为MK-8(H₄)。菌株R7^T的主要极性脂质包括磷脂酰乙醇胺、二磷酸甘油酯、磷脂酰肌醇、氨基磷糖脂、一种未鉴定的磷脂和两种未鉴定的极性脂质。细胞壁肽聚糖中的诊断二氨基酸为内消旋二氨基庚二酸。根据表型、基因型和系统发育证据，菌株R7^T代表稻杆菌属的一种新种，建议命名为粪便稻杆菌（Oryzobacter faecalis sp. nov.）。模式菌株是R7^T(=GDMCC 1.4961^T= KCTC 59403^T= KACC 23902^T)。
