Understanding adhesion of pseudomonas fluorescens on household surfaces
In this study, three different methods have been used to investigate the bacterial interaction with the substratum, i.e. atomic force microscopy (AFM), spinning disc and micromanipulation.
Development and testing of a novel microcantilever technique for measuring the cohesive strength of intact biofilms
TLDR
A modification of the microcantilever method to quantify the strength of intact bacterial biofilms is presented, finding that it is within the range of size of biofilm fragments observed in the effluents of lab‐scale and full‐scale bioreactors.
Characterisation of bacterial adhesion and removal in a flow chamber by micromanipulation measurements
TLDR
Specific mechanisms of biomass detachment from a surface and optimised cleaning strategies can be postulated usingFlow device analyses and micromanipulation techniques show that the apparent adhesive strength of the biomass increased with the growth time and was found to be stronger than the bacterial cohesive strength.
Modulation of the mechanical properties of bacterial biofilms in response to environmental challenges.
TLDR
The current understanding of how the mechanical properties of bacterial biofilms are altered by different environmental challenges is summarized and initial insights into the relationship between these responses and the composition of the matrix are discussed.
Material properties of biofilms-a review of methods for understanding permeability and mechanics.
TLDR
The reader is offered a guide to current technologies that can be utilized to specifically assess the permeability and mechanical properties of the biofilm matrix and its interacting components.
Defined hydrodynamic shear stresses influence the adhesion behaviors of marine Bacillus sp. on stainless steel in artificial seawater
Mechanical properties of the superficial biofilm layer determine the architecture of biofilms.
TLDR
The application of atomic force microscopy and confocal imaging is described to probe in situ the mechanical properties of these interfacial regions and to elucidate how key matrix components can contribute to the physical sensing by the cells.

Direct measurement of the adhesive strength of biofilms in pipes by micromanipulation
TLDR
A novel micromanipulation technique has been developed to measure directly the adhesive strength of biofilms formed in pipe flows, with a typical value of 0.05∼0.2 J/m2.
Influence of electric fields and pH on biofilm structure as related to the bioelectric effect
TLDR
The consequences of the explanation of the increased susceptibility of biofilm cells to antibiotics in an electric field, the "bioelectric effect," are discussed.
Effect of surface shear stress on the attachment of Pseudomonas fluorescens to stainless steel under defined flow conditions
TLDR
The adhesive properties of the bacterium Pseudomonas fluorescens to stainless steel were found to be highly dependent on surface shear stress and the time and concentration of cells used in the incubation procedure.
Effects of biocide and nutrient availability on microbial contamination of surfaces in cooling-water systems
The results of an evaluation of the effects of different factors on formation, growth and removal of biological films are reported. Experiments have been performed both on laboratory equipment and a
Characterization of initial events in bacterial surface colonization by two Pseudomonas species using image analysis
TLDR
These processes have been measured individually in situ in a flowing system in real time using image analysis to study the processes leading to bacterial colonization on solidwater interfaces with different substrata and 2 different bacterial species.
The structure of Pseudomonas fluorescens biofilms in contact with flowing systems
