Abstract

A novel bacterial strain, designated BS-T2-15, isolated from forest soil in close proximity to decaying oak wood, was characterized using a polyphasic taxonomic approach. Phylogenetic analyses based on 16S rRNA gene sequences as well as phylogenomic analyses based on coding sequences of 340 concatenated core proteins indicated that strain BS-T2-15 forms a distinct and robust lineage in the branch of the order . The amino acid identity and the percentage of conserved proteins between the genome of strain BS-T2-15 and genomes of closely related type strains ranged from 64.27 to 66.57% and from 40.89 to 49.27 %, respectively, providing genomic evidence that strain BS-T2-15 represents a new genus. Its cells are Gram-stain-negative, aerobic, motile by a polar flagellum, rod-shaped and form incrusted white to ivory colonies. Optimal growth is observed at 20-22 °C, pH 6 and 0% NaCl. The predominant fatty acids of strain BS-T2-15 are C ω7, C and C 2-OH. Its polar lipid profile consists of a mixture of phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol and its main respiratory quinone is ubiquinone 8. The estimated size of its genome is 6.28 Mb with a DNA G+C content of 69.56 mol%. Therefore, on the basis of phenotypic and genotypic properties, the new strain BS-T2-15 represents a novel genus and species for which the name gen. nov., sp. nov., is proposed. The type strain is BS-T2-15 (DSM 113115=UBOCC-M-3373).

摘要

一株新型细菌菌株,BS-T2-15,从临近腐朽橡木的森林土壤中分离得到,通过多相分类学方法进行了特征描述。基于 16S rRNA 基因序列的系统发育分析以及基于 340 个串联核心蛋白编码序列的系统发育分析表明,BS-T2-15 菌株形成了一个独特而强大的谱系,位于目分支的。BS-T2-15 菌株的基因组与密切相关的模式菌株的基因组之间的氨基酸同一性和保守蛋白百分比分别在 64.27%至 66.57%和 40.89%至 49.27%之间,这为基因组证据表明 BS-T2-15 菌株代表了一个新的属。它的细胞革兰氏阴性,好氧,通过极生鞭毛运动,呈杆状,形成镶嵌的白色到象牙色菌落。最佳生长条件为 20-22°C、pH 值 6 和 0%NaCl。BS-T2-15 菌株的主要脂肪酸为 Cω7、C 和 C 2-OH。其极性脂谱由磷脂酰乙醇胺、双磷脂酰甘油和磷脂酰甘油组成,主要呼吸醌为泛醌 8。其基因组大小估计为 6.28Mb,GC 含量为 69.56mol%。因此,基于表型和基因型特性,新菌株 BS-T2-15 代表了一个新的属和种,建议命名为 属,新种,BS-T2-15 株(DSM 113115=UBOCC-M-3373)。
