Poster: Biofilm formation dynamics under different growth conditions


Bacteria in biofilms are known to better resist disinfectants, cleaning procedures and even antibiotic attack. In this poster, we present experimental data of biofilm population growth at different times in different growing conditions. In particular, stirring of culture medium greatly enhances biofilm growth. Bacterial population dynamics can be satisfactorily modelled by a simple population dynamics model with reasonable assumptions. Using the model we can approximately explain the different growth behavior observed in shaking versus static conditions.
