Free cell or planktonic cells, biofilms, dispersed cells

To understand the concept of biofilms we must know three phenotypes of bacteria

  • Planktonic cells- These are free cells or free-floating cells. In other words, they are not attached to any surfaces. Examples- culturing bacteria in the flask (in the lab) with 200 rpm, acute bacterial infection in the blood.
  • Biofilms- These are surface-attached bacteria. The biofilm formation may be divided into phases- initiation includes a bacterial approach to surface and adhering, followed by microcolony formation, mature biofilms 
  • Dispersed cells- these are bacterial cells which come out from biofilms. This part is not very very clear amongst the biofilm world.
