The Sulfate-Rich and Extreme Saline Sediment of the Ephemeral Tirez Lagoon: A Biotope for Acetoclastic Sulfate-Reducing Bacteria and Hydrogenotrophic Methanogenic Archaea

Figure 6

The phylogenetic tree is showing the relationship of McrA from Tirez sediments with McrA sequences of characterized MA (supplementary material, Table S2). The blue circle identifies the summer phylotypes, and red circle is for the winter phylotypes. Halophilic known species are underlined. The scale bar represents 0 ± 1 substitutions per aa position. Percentages ≥ 50% of bootstrap are indicated near the nodes. See Section 2 to observe details of the phylogenetic reconstruction done for this tree.
