Cell-to-cell communication
- A biofilm is formed and maintained via cell-to-cell communication. A biofilm first forms when one or a few cells attach to a surface. These first cells produce proteins that act as signals to nearby cells. The signals are detected by neighboring cells and essentially recruit new cells into the colony.

Aug 6, 2017 · A biofilm is formed and maintained via cell-to-cell communication. A biofilm first forms when one or a few cells attach to a surface. These first cells produce proteins that act as signals to nearby cells.
Feb 26, 2024 · Biofilm formation is a cyclic process that involves the attachment of free-floating bacteria to a surface, the growth of a microcolony, secretion of the biofilm matrix, and dispersion, which enables bacteria to spread and colonize new surfaces.
Dec 24, 2022 · Biofilm is an aggregate of microorganisms in which cells adhere to each other on a surface. These cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS). Biofilm EPS, also referred to as slime, is a polymeric conglomeration composed of extracellular DNA, proteins, and polysaccharides.
Feb 6, 2023 · The microorganisms that form biofilms include bacteria, fungi, and protists. Perhaps the most common biofilm familiar to most is dental plaque — that sticky, colorless film of bacteria and...

How is it formed? Biofilm formation can be divided into five stages: Initial reversible attachment (1), irreversible attachment (2-3), maturation (4) and dispersion (5) as shown in Figure 2. The initial contact of the moving planktonic bacteria with the surface is the starting point, which is still reversible at this stage.
Summary. Biofilms are complex communities of microbes that are bound by an extracellular macromolecular matrix produced by the residents. Biofilms are the predominant form of microbial life in the natural environment and although they are the leading cause of chronic infections, they are equally deeply connected to our ability to bioremediate waste and toxic materials.
Aug 3, 2022 · We aim to present a simplistic developmental model for biofilm formation that is flexible enough to include all the diverse scenarios and microenvironments where biofilms are formed.
