Fig. 4

Maximum likelihood based phylogenetic tree of almost complete 16S rRNA gene sequences from pure SOB cultures obtained from digesters (Dg) A-F. Their respective type strains are indicated with a superscripted T. Tistrella mobilis served as out-group. Maximum likelihood calculations were based on the Tamura-Nei model [37] and the tree with the highest log likelihood (-4678.6398) is shown. A discrete Gamma distribution was used to model evolutionary rate differences among sites (5 categories (+G, parameter = 0.3865))
