WebBiofilm formation is a strategy by which microorganisms survive and adapt to the involving environment, particularly adverse conditions. The development of a biofilm includes attachment of cells to a surface, multiplication, maturation, and production of a polymeric matrix, and finally microbial detachment and colonization of new surfaces. A biofilm comprises any syntrophic consortium of microorganisms in which cells stick to each other and often also to a surface. These adherent cells become embedded within a slimy extracellular matrix that is composed of extracellular polymeric substances (EPSs). The cells within the biofilm produce the EPS components, which are typically a polymeric conglomeration of extracellular pol… imagine at south vero school
