WebFactors that affect the biofilm development and play important role in its formation are the following: 1. Surface properties: roughness, polarization, oxide coverage, chemical composition such as pH, medium concentration, organic and inorganic strength; all these factors have significant impact on bacterial attachment and biofilm development. 2. WebJul 10, 2024 · Roughness provided a measure of how much the thickness of the biofilm varied and was thus an indicator of biofilm heterogeneity . A roughness with a value of zero indicates a biofilm of uniform thickness, and the greater the roughness coefficient, the rougher the surface. The maximum thickness (μm) of biofilms was determined directly …
