Biofilm microorganisms
WebSometimes waterborne germs, like bacteria, fungi, and amebas, live together in a group, called a biofilm. A biofilm releases a slimy, glue-like substance. This slime allows the germs to stick to surfaces. The slime keeps water treatment chemicals, such as chlorine, away from the germs, which helps the germs survive and multiply.

WebA biofilm is an architectural colony of microorganisms, within a matrix of extracellular polymeric substance that they produce. Biofilm contains microbial cells adherent to one-another and to a static surface (living or non-living). Bacterial biofilms are usually pathogenic in nature and can cause nosocomial infections. WebA biofilm includes three components: Microorganisms that adhere, or stick, to one another or a surface. A change in the microorganisms’ state from their single-celled “planktonic” state to their “biofilm state”. 1 This...
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…
