Maximum likelihood based phylogenetic tree showing the most dominant species in enrichment cultures from digesters (Dg) A-F regarding DGGE analyses (partially 16S rRNA gene sequences, 550 bp) and their respective type strains. Sulfur oxidizing genera are marked in bold. The evolutionary history was inferred using the Maximum Likelihood method based on the Kimura 2-parameter model [36]. The tree with the highest log likelihood (-4546.7510) is shown. A discrete Gamma distribution was used to model evolutionary rate differences among sites (5 categories (+G, parameter = 0.5303)). The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. Evolutionary analyses were conducted with MEGA6
