Kinetics of the AHL Regulatory System in a Model Biofilm System: How Many Bacteria Constitute a “Quorum”?

Acylated homoserine lactones (AHLs) regulate a wide variety of phenotypes in Gram-negative bacteria. Most research suggests that AHL-mediated phenotypes are not expressed in populations until late logarithmic phase or stationary phase. Here, we model how the concentration of AHLs inside bacterial ce...
