Phylogenetic analysis of three anammox microbial communities. a A maximum likelihood tree based on the alignment of 15 concatenated ribosomal proteins. In the construction of the tree 3225 reference sequences were used, with genomes from current and previous genome-centric studies on anammox communities. Genomes from the current anammox community are marked with a red dashed line, genomes from two previously studied communities, Speth et al. and Lawson et al., are marked with green and blue dashed lines, respectively. Nodes containing only reference genomes were collapsed for ease of view. Collapsed nodes are depicted as triangles and their size is relative to the number of bacteria they contain. The black star marks Brocadia. b Relative abundance of major phyla in the three microbial communities. Current community reference data was calculated from Day 437 only. The relative abundance of Brocadia sp. comprises nearly all of the relative abundance attributed to phylum Planctomycetes (with small contributions from other members of the phylum). The most abundant phyla (Chloroflexi, Ignavibacteria, and Proteobacteria) consistently account for > 70% of the communities. The phyla colors follow the ggkbase color scheme and the major phyla are shown in the legend
