Biofilm microbiology
WebIntroduction. Bacterial biofilms are microbial communities adhered to an inert surface or to a tissue, and are encased within a complex matrix. Their formation involves several stages: planktonic bacteria attach themselves reversibly to a surface, form a microcolony and produce a polymer matrix around the biofilm [1].
