How biofilm is formed
WebBiofilm formation is a complex process involving five main phases: (i) reversible attachment, where bacteria non-specifically attach to surfaces; (ii) irreversible attachment, which involves interaction between bacterial cells and a surface using bacterial adhesins such as fimbriae and lipopolysaccharide (LPS); (iii) production of extracellular … WebBiofilm formation is a natural phenomenon which occurs wherever there are microorganisms and surfaces – whether only slightly wet or immersed, and whether …
