Biofilm irreversible attachment

WebDec 15, 2015 · In the environment, most bacteria form surface-attached cell communities called biofilms. The attachment of single cells to surfaces involves an initial reversible stage typically mediated by surface structures such as flagella and pili, followed by a permanent adhesion stage usually mediated by polysaccharide adhesives. WebIrreversible attachment can be achieved by species-specific adhesins on the cell surface that bind to the substrate and withstand detaching forces. ...
