WebSep 23, 2024 · Generally, the microbial biofilm develops on a substratum and is immersed in polymeric matrix that is secreted by the bacteria. Both auto and hetero-trophic microbes form stable biofilms for their survival in harsh conditions. 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.
