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.
Aug 11, 2016 · Bacterial biofilms are formed by communities that are embedded in a self-produced matrix of extracellular polymeric substances (EPS). Importantly, bacteria in biofilms...

Bacterial biofilms are clusters of bacteria that are attached to a surface and/or to each other and embedded in a self-produced matrix. The biofilm matrix consists of substances like proteins (e.g., fibrin), polysaccharide (e.g., alginate), as well as eDNA.
Many different bacteria form biofilms, including gram-positive (e.g. Bacillus spp, Listeria monocytogenes, Staphylococcus spp, and lactic acid bacteria, including Lactobacillus plantarum and Lactococcus lactis) and gram-negative species (e.g. Escherichia coli, or Pseudomonas aeruginosa). [88]
Schematic representation of a biofilm formation. The formation begins with a reversible attachment of the planktonic cells (brown ovals) followed by the adhesion to the surface (grey) (1). The bacteria then form a monolayer and irreversibly attach by producing an extracellular matrix (2).
Parsek and Singh 80 propose four criteria for defining a biofilm aetiology of an infection: the pathogenic bacteria are surface associated or adherent to a substratum; direct...
Sep 30, 2014 · Biofilm formation is commonly considered to occur in four main stages: (1) bacterial attachment to a surface, (2) microcolony formation, (3) biofilm maturation and (4) detachment (also termed dispersal) of bacteria which may then colonize new areas [2].
