The dynamics of structural characteristics of biofilms (A) cell biomass, (B) average thickness, (C) roughness coefficient, and (D) surface area to volume ratio for 168 days of biofilm growth under HS-, AOM- and R2A-impacted bulk water. Minimum eight randomly selected locations in a coupon were imaged for each biofilm sample. Error bars indicate standard deviation among different locations (n ≥ 8).
