Internal biofilm matrix pore diameters ranged from 1 to 205.2 μm, with a distribution that favored pores and channels smaller than 10 μm, and a mean equivalent spherical diameter of 8.6 μm.
WebApr 11, 2024 · The basis to determine biofilm thickness was z‐images of a 185 µm wide area taken on ten randomly chosen sections on the biofilm. For optimum analysis laser intensity should be chosen in a way that the biofilm is clearly distinguished but not overexposed. The Syto9 fluorescence signal was subsequently used as input for … WebThe thickness of biofilms is an important parameter for scientists and engineers to know because it is related to the rate of growth of the biofilm and the extent to which biofilms interfere with human engineered …
