Figure 1: Phylogenetic analysis of WWTP AAW.
From: Limited dissemination of the wastewater treatment plant core resistome
(a) The pairwise similarity of the microbial community in samples collected from the WWTP AAW over a 7-year period (n=24). Similarity is calculated as (1−Bray–Curtis dissimilarity index) × 100 for each pairwise comparison of 16S rRNA amplicons and plotted against the time (years) between the samples. (b) Per cent abundance of the ten most abundant bacterial orders in WWTP AAW over a 7-year period. On average, 68% (s.d.=4%, n=24) of the 16S rRNA gene sequences belong to these orders.
