Abstract

DHUNG17 was compared with XHP0097 to examine the taxonomic relationship between the two type strains. The 16S rRNA gene sequence of DHUNG17 shared high similarity (99.9 %) to that of XHP0097. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus . The average amino acid identity, average nucleotide identity and digital DNA-DNA hybridization values between DHUNG17 and XHP0097 were below 99.0, 99.1 and 92.2±1.7 %, respectively, all of which were greater than the species delineation threshold for AAI (95.5 %), ANI (95-96 %) and dDDH (70 %), strongly indicating that the two strains represented a single species. Based on the combined phylogenetic, genomic and phenotypic characterization presented here, we propose as a later heterotypic synonym of .

摘要

将DHUNG17与XHP0097进行比较，以研究这两个模式菌株之间的分类关系。DHUNG17的16S rRNA基因序列与XHP0097的序列具有高度相似性（99.9%）。基于16S rRNA基因序列的系统发育分析结果表明，这两个菌株在该属内形成了一个紧密的聚类。DHUNG17与XHP0097之间的平均氨基酸同一性、平均核苷酸同一性和数字DNA-DNA杂交值分别低于99.0%、99.1%和92.2±1.7%，所有这些值均大于AAI（95.5%）、ANI（95-96%）和dDDH（70%）的物种界定阈值，强烈表明这两个菌株代表一个单一物种。基于此处呈现的系统发育、基因组和表型特征的综合分析，我们提议将[具体名称1]作为[具体名称2]的晚出异名。
