A Gram-positive, alkaliphilic bacterium, designated strain BA288(T), was isolated from sandy soil. Cells were facultatively anaerobic, endospore-forming rods that were motile by means of peritrichous flagella. The strain grew at 15-40 degrees C and pH 7.0-11.0 (optimally at 30 degrees C and pH 9.0-9.5) and at salinities of 0-4 % (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain BA288(T) belonged to the genus Bacillus and that Bacillus herbersteinensis D-1,5a(T), Bacillus humi LMG 22167(T), Bacillus cohnii DSM 6307(T) and Bacillus litoralis SW-211(T) were the closest neighbours (96.2, 96.0, 96.0 and 95.9 % sequence similarity, respectively). The genomic DNA G+C content was 37.9 mol% and the predominant menaquinone was MK-7. The major cellular fatty acids were anteiso-C(15 : 0), iso-C(15 : 0), C(16 : 0) and iso-C(14 : 0). The peptidoglycan type was A1gamma (meso-diaminopimelic acid). Therefore, on the basis of phylogenetic, phenotypic and chemotaxonomic properties, strain BA288(T) represents a novel species of the genus Bacillus, for which the name Bacillus alkalitelluris sp. nov. is proposed. The type strain is BA288(T) (=KCTC 3947(T) =DSM 16976(T)).
从沙质土壤中分离出一株革兰氏阳性嗜碱细菌,命名为菌株BA288(T)。细胞为兼性厌氧、产芽孢杆菌,通过周生鞭毛运动。该菌株在15 - 40℃和pH 7.0 - 11.0条件下生长(最适生长温度为30℃,最适pH为9.0 - 9.5),在NaCl浓度为0 - 4%(w/v)的盐度下也能生长。基于16S rRNA基因序列的系统发育分析表明,菌株BA288(T)属于芽孢杆菌属,与赫伯斯坦芽孢杆菌D-1,5a(T)、土壤芽孢杆菌LMG 22167(T)、科氏芽孢杆菌DSM 6307(T)和滨海芽孢杆菌SW-211(T)是最接近的亲缘种(序列相似性分别为96.2%、96.0%、96.0%和95.9%)。基因组DNA的G+C含量为37.9 mol%,主要的甲基萘醌为MK-7。主要的细胞脂肪酸为anteiso-C(15 : 0)、iso-C(15 : 0)、C(16 : 0)和iso-C(14 : 0)。肽聚糖类型为A1γ(内消旋二氨基庚二酸)。因此,基于系统发育、表型和化学分类学特性,菌株BA288(T)代表芽孢杆菌属的一个新物种,为此提出新名称嗜碱土芽孢杆菌(Bacillus alkalitelluris sp. nov.)。模式菌株为BA288(T)(=KCTC 3947(T) =DSM 16976(T))。
