Figure 2
Relative abundance expressed as percent of total 16S rDNA reads and colonization kinetics of the main bacterial phyla over 236 days of the SM_WWTP colonization. (A) Relative abundance (%) of bacteria at the phylum taxonomic level within the 23 time-series SM_WWTP samples. Nine phylogenetic groups (in bold) represent up to 97.6% of the total reads. Colored lines delimit the three periods of bacterial evolution. Pink represents the first period, blue, the intermediate period, and green represents the third period. (B) Colonization kinetics of Proteobacteria and Bacteroidetes. Scale color: blue for Proteobacteria; red for Bacteroidetes. (C) Colonization kinetics of Actinobacteria and Firmicutes. Scale color: blue for Firmicutes; red for Actinobacteria. (D–G) Colonization kinetics of the remaining major bacterial phyla representing the late colonizers (D,E), and the first and late Proteobacteria colonizers at the phylogentic order level, in (F,G). (H,I) Bacteroidetes colonization kinetics at the phylogenetic order level over the 236 days of microbiota evolution within the SM_WWTP. The first colonizers (H) and late colonizers (I). Y-axis scale color: Green, for Flavobacteriales only, pink, for Latescibacteria only.
