FIGURE 7

Bar graph representing relative proportions of significant KEGG Pathways at level 3 of SEED metabolic hierarchy in biofilms from contaminated (6ext; red) and uncontaminated (41p; green) sites (A), and in biofilms from surface (yellow) and bottom (blue) (B). Extended error bar plots showed pairwise comparison of significant KEGG Pathway proportions (Welch’s t-test; p < 0.01) at level 3 of SEED metabolic hierarchy between biofilms from contaminated (6ext; red) and uncontaminated (41p; green) sites (A), and between biofilms from surface (yellow) and bottom (blue) (B). Corrected p-value is determined using Fisher’s exact test.
