- "Razan Alnahhas 17:22, 30 March 2012 (EDT)":You wrote that QS has been used in synthetic biology as a biosensor for harmful bacteria, so could the QS system that monitors AHL levels be engineered to also respond to high concentrations of AHL by producing an antibiotic to kill the bacteria?
- Yi Kou 12:24, 1 April 2012 (EDT):I am kind of interested in whether cell membrane permeability of the inducer interferes with the result; the system seems to be easily interrupted by different kinetics of inducer in and out the cell membrane.
- Jeffrey E. Barrick 18:02, 1 April 2012 (EDT):In some cases, at least, it seems that quorum sensing is used for other purposes than for bacteria to "determine their densities". It may be used to determine how much flow is happening around a little clump of cells ("diffusion sensing" - kind of like testing the wind) . The idea is that throwing out metabolically "cheap" compounds can let you determine whether making more costly things like extracellular siderophores or proteases is worth doing, or whether they would float away too quickly to give you a benefit.
