WebBiofilms are complex living materials that form as bacteria become embedded in a matrix of self-produced protein and polysaccharide fibers. In addition to their traditional association with chronic infections or clogging of pipelines, biofilms currently gain interest as a potential source of functional material. On nutritive hydrogels, micron-sized Escherichia coli cells … WebApr 29, 2024 · Here, we consider one of the simplest confined geometries: a biofilm growing laterally in the space between a solid surface and an overlying elastic sheet. A poroelastic framework is utilized to derive the radial growth rate of the biofilm; it reveals …
WebMay 6, 2015 · Although in both biofilms an initial elastic response was clear, residual deformation was observed after the stress was removed (figures 1b,c, t = 120 s). Analysis of biofilm deformation under the highest flow condition is presented in figure 2. Strain over time is shown for the sloughing event observed in the lower viscosity biofilm and a ... WebWe present dimensionless shallow layer scalings that reduce the system of equations describing the full system (2)-(6) in the main text to a pair of coupled differential equations for the height h ( r, t ) and vertically averaged biomass volume fraction (cid:104) φ (cid:105) ( r, t ) as a function of radial distance r and time t .

WebOct 7, 2024 · Biofilms buildup internal mechanical stress as single cells grow within the elastic matrix. By combining mechanical measurements and mutations in matrix components, we found that biofilms deform by buckling, and that adhesion transmits these forces to their substrates.
WebOct 15, 2001 · Biofilm formation is a process whereby microorganisms irreversibly attach to and grow on a surface and produce extracellular polymers that facilitate attachment and matrix formation, resulting in an alteration in the phenotype of the organisms with respect to growth rate and gene transcription.
WebAug 9, 2024 · Biofilm growth occurs at the biofilm-fluid interface by a stochastic rule that depends on the local nutrient concentration.
