Deposition Efficiency and Reversibility of Bacterial Adhesion under Flow

Processes in microbial transport in the natural subsurface

“…Similar conclusions have been reached by the observation of Escherichia coli taxis along a glass surface; the bacteria-surface interactions could not be explained by DLVO theory [124]. Although DLVO theory has been extended to include acid-base (hydrophobic) interactions [122], hydrophobic interactions are often negligible under common conditions of subsurface bacterial transport [79,112].…”

Application of Scanning Electron Microscopy for the Morphological Study of Biofilm in Medical Devices

“…This has some importance since the initial adhesion often develops into a stronger interaction with time (bond ageing) (Meinders et al, 1995). The reduction in the amount of exopolysaccharides (EPS) in the presence of NAC may have many explanations.…”

Understanding particle deposition kinetics on NF membranes: A focus on micro-beads and membrane interactions at different environmental conditions

“…Key parameters include the effects of hydrodynamics and its effect on mass transfer rate, the surface properties of the membrane and bacteria, liquid solution properties such as pH and ionic strength, as well as permeate drag exerted on bacteria [6][7][8][9][10][11][12].…”

“…In an earlier study in which bacterial adhesion under dynamic conditions was investigated onto different surfaces, Meinders and colleagues demonstrated that it was possible to study mass transfer processes precisely under constant flow experimental conditions [10]. The effect of mass transfer on bacterial adhesion can generally be described by the adsorption-desorption kinetic model.…”

“…The effect of mass transfer on bacterial adhesion can generally be described by the adsorption-desorption kinetic model. The potential adhesion area is blocked by the previous adhered microorganisms and this blocking effect leads to the equilibrium status [10,13]. Bacterial adhesion onto membranes was also shown to be associated with to the surface physicochemical properties of both bacteria and substrate.…”
