Abstract:
A mathematical model is presented that describes the disinfection of
microbial biofilms by antibiotics.
It is the first multi-species/multi-substrate generalization of a
continuous prototype biofilm model comprising degenerating
as well as fast diffusion. The boundedness of the model solution is
established. The dynamic model behaviour in dependence of model parameters
is studied by numerical simulations.
A characteristic dimensionless parameter, the disinfection number,
is derived, allowing an a priori statement whether all active
biomass will be removed or not.
