A Gram-positive, rod-shaped, spore-forming, thermophilic, and acidophilic bacterium, designated as strain skT53, was isolated from farm soil in Tokyo, Japan. Under aerobic conditions, the strain grew at 35-55 °C (optimum temperature 44-55 °C) and pH 4.0-6.0 (optimum pH 5.0). Phylogenetic analysis of the 16S rRNA gene sequence showed that the isolate was moderately related to the type strain of Effusibacillus consociatus (94.3% similarity). The G + C content of the genomic DNA was 48.2 mol%, and MK-7 was the predominant respiratory quinone in the strain. The major fatty acids were anteiso-C, iso-C, and iso-C. Based on the phenotypic and chemotaxonomic characteristics, as well as 16S rRNA gene sequence similarity and whole genome analyses, strain skT53 represents a novel species in the genus Effusibacillus, for which the name Effusibacillus dendaii sp. nov. has been proposed. The type strain is skT53 (= NBRC 114101 = TBRC 11241).
一株革兰氏阳性、杆状、产孢、嗜热、嗜酸的细菌,被命名为 skT53 菌株,从日本东京的农田土壤中分离得到。在好氧条件下,该菌株在 35-55°C(最佳温度 44-55°C)和 pH4.0-6.0(最佳 pH5.0)的条件下生长。16S rRNA 基因序列的系统发育分析表明,该分离株与协同埃弗拉塔斯氏菌(Effusibacillus consociatus)的模式株中度相关(相似度为 94.3%)。基因组 DNA 的 G+C 含量为 48.2mol%,菌株中的主要呼吸醌为 MK-7。主要脂肪酸为 anteiso-C、iso-C 和 iso-C。基于表型和化学分类特征以及 16S rRNA 基因序列相似性和全基因组分析,菌株 skT53 代表埃弗拉塔斯氏菌属中的一个新种,现提议将其命名为 dendaii 埃弗拉塔斯菌(Effusibacillus dendaii)。模式菌株为 skT53(=NBRC 114101=TBRC 11241)。
