WebBiofilm formation can occur at any given surface if the environment contains protein and other molecules. The formation initiates with the microbes attaching to the conditioned surface [2, 3]. Gradually, the microbes form a slimy matrix of various polymers which is called an extracellular matrix (ECM) or an extracellular polymeric substance (EPS). WebA biofilm is a structured consortium of bacteria embedded in a self-produced polymer matrix consisting of polysaccharide, protein and DNA. Bacterial biofilms cause chronic infections because they show increased tolerance to antibiotics and disinfectant chemicals as well as resisting phagocytosis and other components of the body's defence system.
