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 eps the cells within the biofilm produce the eps components which are typically a polymeric conglomeration of extracellular

a general definition and characteristics of a biofilm can be found here the quot conditioning film quot which is a layer of organic molecules including lipids and proteins deposited from tears onto the contact lenses is the surface that the microbe first binds and absorbs to with the help of the quot conditioning film quot the microbes are able to reach the contact lenses

scientists call it biofilm and it x27 s a type of bacterial colony the produces a sticky organic glue which anchors the organisms to each other and to whatever surface they fancy
