WebFeb 16, 2024 · toxicity sensors. Bacterial biofilms are aggregates of microorganisms in which cells are embedded in a self-produced matrix of extracellular polymeric substances (EPSs). (1−6) This condition is significantly different from planktonic bacteria, where bacterial cells freely move in a bulk solution. 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. cswea 2023
