Biofilm sloughing
WebBiofilm sloughing is an integral aspect, and a dynamic activity of biofilm development. This study focused on biofilm sloughing on carriers in integrated fixed-film activated sludge (IFAS) systems in both laboratory (LS; synthetic feed) and full-scale (FS; municipal) systems. During biofilm development in the LS system the relative ... WebBiofilm formation begins with the adherence of bacteria to a tooth surf ace, followed by a lag phase in which changes in genetic expression (phenotypic shifts)occur. A period of rapid growth then occurs, and an exopolysaccharide matrix is produced. During the steady state, the biofilm reaches growth equilibrium. Surface detachment and sloughing

WebThe predicted features included centrally located voids appearing in sufficiently large cell clusters, gradients in growth rate within these clusters, and the release of most of the biofilm with simulated stopped-flow conditions. The model was also able to predict biofilm sloughing resulting solely from this detachment mechanism. WebSloughing is more random than erosion and is thought to result from nutrient or oxygen depletion within the biofilm structure . Sloughing is more commonly observed with …

WebBiofilm sloughing is considered an integral part of biofilm development [16, 17]. In fixed-film wastewater treatment systems, biofilms grow under con-tinuous hydrodynamic and shear pressures facilitating the mass transport to the core and forming compact biofilms [18].
