WebThese researchers’ results showed that different organisms produce differing amounts of EPS and that the amount of EPS increases with age of the biofilm. EPS may associate with metal ions, divalent cations, other macromolecules (such as proteins, DNA, lipids, and even humic substances) ( 38 ).
WebJan 26, 2016 · The bacteria in the phase of maturation also produce the extracellular matrix which provides a three-dimensional structure to the biofilm. Autotransporters (for cell-to-cell interaction) and EPS (for matrix formation) are both crucial for biofilm maturation. WebIn a next step, bacteria proliferate and produce the EPS. Finally, the biofilm matures and bacteria are released into the surrounding area. Taking into account that maturated bacterial biofilms exhibit increased resistance to removal and to chemical and antibiotic treatment, it is desirable to prevent the initial bacterial adhesion.
WebApr 7, 2024 · Bacteria are tiny organisms that we cannot see with our naked eye. In nature they live in social groups called biofilms.
