      Genome-based classification of two halotolerant extreme acidophiles, Acidihalobacter prosperus V6 (=DSM 14174 =JCM 32253) and 'Acidihalobacter ferrooxidans' V8 (=DSM 14175 =JCM 32254) as two new species, Acidihalobacter aeolianus sp. nov. and Acidihalobacter ferrooxydans sp. nov., respectively.

          Abstract

          Phylogenomic analysis of recently released high-quality draft genome sequences of the halotolerant acidophiles, Acidihalobacter prosperus V6 (=DSM 14174=JCM 32253) and 'Acidihalobacter ferrooxidans' V8 (=DSM 14175=JCM 32254), was undertaken in order to clarify their taxonomic relationship. Sequence based phylogenomic approaches included 16S rRNA gene phylogeny, multi-gene phylogeny from the concatenated alignment of nine selected housekeeping genes and multiprotein phylogeny using clusters of orthologous groups of proteins from ribosomal protein families as well as those from complete sets of markers based on concatenated alignments of universal protein families. Non-sequence based approaches for species circumscription were based on analyses of average nucleotide identity, which was further reinforced by the correlation indices of tetra-nucleotide signatures as well as genome-to-genome distance (digital DNA-DNA hybridization) calculations. The different approaches undertaken in this study for species tree reconstruction resulted in a tree that was phylogenetically congruent, revealing that both micro-organisms are members of separate species of the genus Acidihalobacter. In accordance, it is proposed that A. prosperus V6T (=DSM 14174 T=JCM 32253 T) be formally classified as Acidihalobacter aeolianus sp. nov., and 'Acidihalobacter ferrooxidans' V8T (=DSM 14175 T=JCM 32254 T) as Acidihalobacter ferrooxydans sp. nov., and that both represent the type strains of their respective species.
