Figure 3.
Log2 fold change comparison between the relative abundance of bacterial families in untreated sewage and biofilm. Families more abundant in sewage are represented using green bars, while families more abundant in biofilm are in orange. Relative abundance of the families per compartment are listed on the left of the plot. The relative abundance per family was computed by averaging the abundances pondered with the number of sample from the publications described in the Figure 1. Relative abundance higher than 10% are in bold. Only the families with a relative abundance higher than 1% in at least one of the two compartments were considered.
