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]. Environmental biofilms are organized mixed microbial aggre- WebThe third phase starts with the sloughing of large biofilm patches from well-grown biofilms, and the final stage consists of biofilm regrowth and the expansion of the spatial coverage. The catalytic performance of the mixed-species biofilm after the detachment process was compared to a well-grown biofilm. With an increase in the biofilm surface ...

WebAug 31, 2024 · The structure of biofilms in drinking water systems is influenced by the interplay between biological and physical processes. Bacterial aggregates in bulk fluid are important in seeding biofilm formation on surfaces. In simple pure and co-cultures, certain bacteria, including Methylobacterium, are implicated in the formation of aggregates. … 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.
