Figure 4. Genus-level phylogenetic analysis (Illumina MiSeq) revealed the temporal changes in the bacterial community structures in various aerobic sewage treatment samples.

(A) Lewinella was commonly detected in all sewage treatments. (B) Pseudomonas was slightly enriched in the testosterone-treated aerobic sewage. (C) Comamonas was highly enriched in the testosterone-treated aerobic sewage. The pie chart represents the relative abundances of individual Comamonas spp. (100%) in the sewage incubated with testosterone for 48 hours. See Supplementary Fig. S2 for detailed information.
