Iron in bacterial biofilms
Web21 hours ago · Introduction. Adhesion of bacterial cells to abiotic and biotic surfaces is crucial for the colonization of new environments, including host invasion during infections and biofilm formation [1–5].Bacterial adhesion is often mediated by proteinaceous, hair-like cell-surface structures known as pili or fimbriae [6,7].Pili are assembled by repeated …
