WebQuorum sensing is a communication process that allows bacteria within a biofilm to coordinate their behavior and respond to changes in their environment. Biofilms can pose a problem in medical settings, such as on medical implants, where they can lead to infections that are difficult to treat with antibiotics. Web1. Take cultured cells at luminescent stage. 2. Remove the bacterial cells and leave the supernatant. The molecules that can produce light are in the supernatant. 3. Add this supernatant to normal, original bacteria, and there will now be no lag phase in luminescence (open shape curve).
