Phylogenetic tree based on 16S rRNA sequences showing the phylogenetic position of Thioalkalivibrio sp. K90mix. The sequence was aligned to sequences stored in the SILVA database using the SINA Webaligner [24]. Subsequently, the aligned sequences were imported into ARB [25], and a neighbor joining tree was constructed. Sequences of members from the Alphaproteobacteria were used as outgroup, but were pruned from the tree. The scale bar indicates 1% sequence difference.
