The present study aimed to examine the taxonomic relationship between two species, Ghosh . 2006 and (Harrison 1983) Katayama . 1996. Comparison of 16S rRNA gene sequences revealed that JJJ was highly similar (99.9 %) to A2. The results of phylogenetic analysis based on 16S rRNA gene sequences indicated that the two strains formed a tight cluster within the genus . Whole genomic comparison between the two strains showed a digital DNA-DNA hybridization estimate of 82. 0 % and an average nucleotide identity value of 98.2 %, clearly indicating that the two strains were members of the same species. Moreover, the type strains of both species shared similar physiological and biochemical properties and fatty acids profiles. Based on genotypic and phenotypic evidence, we conclude that Ghosh . 2006 is a later heterotypic synonym of (Harrison 1983) Katayama . 1996 according to the priority of publication and validation of the name.
本研究旨在探讨两个物种，即 Ghosh. 2006 和 (Harrison 1983) Katayama. 1996 之间的分类关系。16S rRNA 基因序列比较显示，JJJ 与 A2 高度相似（99.9%）。基于 16S rRNA 基因序列的系统发育分析结果表明，这两个菌株在属内形成了一个紧密的聚类。两株之间的全基因组比较显示数字 DNA-DNA 杂交估计值为 82.0%，平均核苷酸同一性值为 98.2%，清楚地表明这两个菌株是同一物种的成员。此外，两个物种的模式株具有相似的生理生化特性和脂肪酸图谱。基于基因型和表型证据，我们得出结论，根据发表时间的优先顺序和名称的验证，Ghosh. 2006 是 (Harrison 1983) Katayama. 1996 的后来的同型异名。
