Quorum sensing

Quorum sensing is a cellular communication process used by bacteria and some other microorganisms to coordinate their behavior based on population density. It enables them to detect and respond to the presence of other cells in their environment through the release and detection of signaling molecules called autoinducers. When the concentration of these signaling molecules reaches a certain threshold, it indicates that a sufficient number of bacterial cells are present. This allows bacteria to trigger collective behaviors that are more effective when executed by a larger group.
