Computational Investigation of Ripple Dynamics in Biofilms in Flowing Systems

Biofilms are collections of microorganisms that aggregate using a self-produced matrix of extracellular polymeric substance (EPS). It has been broadly demonstrated that many microbial infections in the body, including dental plaque, involve biofilms. While studying experimental models of biofilms relevant to mechanical removal of oral biofilms, distinct ripple patterns have been observed. In this paper, we describe a multiphase model used to approximate the dynamics of the biofilm removal process.
