Genomic Analysis Unravels Reduced Inorganic Sulfur Compound Oxidation of Heterotrophic Acidophilic Acidicaldus sp. Strain DX-1

Figure 1

Phylogenetic tree of 16S rRNA genes showing the relationship of strain DX-1 (in bold) to other acidophilic α-Proteobacteria. Phylogenetic tree was constructed based on an alignment of 1283 bp using the neighbor joining method. The scale bar represents 0.01 nucleotide substitutions per 100. And the database accession numbers of the gene sequences used are given in parentheses. Acidisphaera rubrifaciens HS-AP3 was used to root the tree.
