Estimated model parameters of the Geeraerd et al. [25] model obtained following inactivation of the 1-day-old L. monocytogenes and S. Typhimurium single-species model biofilms using the helium-operated SBD system. These model parameters have been discussed in detail in the research of Govaert et al. [13].
