A Gram-staining-positive, motile, rod-shaped, spore-forming bacterium, designated P9(T), was isolated from soil in Portugal. This organism was aerobic and catalase- and oxidase-positive. It had an optimum growth temperature of about 35 °C and an optimum growth pH of about 8.0-8.5, and grew in medium with 0-9% (w/v) NaCl. The cell-wall peptidoglycan was of the A1α type, with L-lysine as the diagnostic diamino acid. The major respiratory quinone was menaquinone 7 (MK-7) and the major fatty acids were anteiso-C(15:0) (45.4%), iso-C(15:0) (22.0%) and anteiso-C(17:0) (11.2%). The genomic DNA G+C content was about 39.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain P9(T) was most closely related to Jeotgalibacillus campisalis DSM 18983(T) (96.8%) and Jeotgalibacillus marinus DSM 1297(T) (96.5%). These two recognized species formed a coherent cluster with strain P9(T) that was supported by a bootstrap value of 99%. On the basis of the phylogenetic analysis and physiological and biochemical characteristics, strain P9(T) (=DSM 23228(T)=LMG 25523(T)) represents a novel species of the genus Jeotgalibacillus, for which the name Jeotgalibacillus soli sp. nov. is proposed.
一株革兰氏染色阳性、运动、杆状、孢子形成的细菌,被命名为 P9(T),从葡萄牙的土壤中分离出来。该菌为需氧菌,过氧化氢酶和氧化酶阳性。最适生长温度约为 35°C,最适生长 pH 值约为 8.0-8.5,可在 0-9%(w/v)NaCl 的培养基中生长。细胞壁肽聚糖为 A1α 型,以 L-赖氨酸为特征二氨基酸。主要呼吸醌为menaquinone 7 (MK-7),主要脂肪酸为anteiso-C(15:0) (45.4%)、iso-C(15:0) (22.0%)和anteiso-C(17:0) (11.2%)。基因组 DNA G+C 含量约为 39.4 mol%。基于 16S rRNA 基因序列的系统发育分析表明,菌株 P9(T)与 Jeotgalibacillus campisalis DSM 18983(T)(96.8%)和 Jeotgalibacillus marinus DSM 1297(T)(96.5%)最为密切相关。这两个公认的种与 P9(T)菌株形成了一个连贯的聚类,支持该聚类的系统发育树自举值为 99%。基于系统发育分析和生理生化特征,菌株 P9(T)=DSM 23228(T)=LMG 25523(T)代表 Jeotgalibacillus 属的一个新种,现命名为 Jeotgalibacillus soli sp. nov.。
