| Title: | Incorporating the biofilm/fluid interface into a comprehensive model of biofilm development. |
| Abstract: |
Biofilms are aggregates of bacteria enmeshed in a polymer gel found in
aqueous solutions. The varied settings for biofilm formation and their
tolerance to antimicrobials have motivated extensive
investigation into the control and disinfection of biofilms. Robust
treatment of the fluid dynamics in mathematical models is important
because the dynamics of both the chemical constituents and material
deformation of the biofilm depend directly on the bulk fluid flow. We
describe a novel method, based on Regularized Stokeslets, to model the system in the case of creeping
flow.
Extensions
of the model to the case of a dynamic interface will also be described.
