WebApr 9, 2024 · A diagram depicting early events in biofilm formation. Planktonic cells that have not previously encountered cells and are exhibiting low cAMP levels are called surface naive. These cells initially exhibit very brief, transient interactions with a surface called reversible attachment.
WebApr 9, 2024 · Following irreversible attachment, cells multiply and start producing biofilm matrix components, forming small aggregates of bacteria called microcolonies. … Webbiofilm matrix and multilayer biofilm formation (Kierek & Watnick, 2003). The second step in biofilm formation requires the cell to form at least a semipermanent association with the surface. This step is frequently referred to as the ‘attachment phase’. Many authors have broken this down into a reversible and an irreversible phase, but with
