Özet

In this study, our aim was to elucidate the relationship between Anoxybacillus rupiensis DSM 17127(T) and Anoxybacillus geothermalis GSsed3(T) through whole-genome phylogenetic analysis. The obtained 16S rRNA gene sequence from the genome of A. rupiensis DSM 17127(T) exhibited a 99.8% similarity with A. geothermalis GSsed3(T). In the phylogenetic trees constructed using whole-genome sequences and 16S rRNA gene sequences, A. rupiensis DSM 17127(T) and A. geothermalis GSsed3(T) were observed to form a clade, indicating a close relationship between them. Moreover, the average amino acid identity, average nucleotide identity, and digital DNA-DNA hybridization values calculated between A. rupiensis DSM 17127(T) and A. geothermalis GSsed3(T) exceeded the threshold values typically used for species demarcation. Furthermore, the phylogenomic analysis based on the core genome of the strains in question provided additional support for the formation of a monophyletic clade by A. rupiensis DSM 17127(T) and A. geothermalis GSsed3(T). Most phenotypic and chemotaxonomic features between both strains were almost identical except for a few exceptions. These findings suggest that both strains should be classified as belonging to the same species, and we propose that A. geothermalis GSsed3(T) is a later heterotypic synonym of A. rupiensis DSM 17127(T).
