WebApr 14, 2024 · The generally accepted model of biofilm formation includes five stages: reversible attachment, irreversible attachment, maturation I, maturation II, and dispersion . Initially, planktonic cells adhere to the surface via a single pole through weak and reversible interactions and can readily detach and return to the planktonic phase. 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
