WebApr 7, 2024 · Biofilm is considered as a continuous conductive structure (conduction-based biofilm model 22), with an equivalent conductivity σ bio, function of the active and inactive biomass fractions. WebThe biofilm also significantly increased in thickness and surface coverage. When C and N concentrations were reduced to their original levels, there was a loss of biomass and the ripples and streamers reappeared. We speculate that cell surface properties, in particular hydrophobicity or hydrophilicity, also can determine the biofilm structure.
