Material properties of biofilms – key methods for understanding

Abstract. Microorganisms can form biofilms, which are multicellular communities surrounded by a hydrated extracellular matrix of polymers. Central properties of the biofilm are governed by this extracellular matrix, which provides mechanical stability to the three-dimensional biofilm structure, regulates the ability of the biofilm to adhere to surfaces, and determines the ability of the

The membrane-biofilm reactor (MBfR) as a counter-diffusional biofilm
