What (who) is Quorum sensing - definition
Quorum sensing
PROCESS IN WHICH SINGLE-CELLED ORGANISMS MONITOR THEIR POPULATION DENSITY BY DETECTING THE CONCENTRATION OF SMALL, DIFFUSIBLE SIGNAL MOLECULES PRODUCED BY THE CELLS THEMSELVES.
Quorum-sensing; Quorum Sensing; Quorum quenching; Quorum signalling
In biology, quorum sensing or quorum signalling (QS) is the ability to detect and respond to cell population density by gene regulation. As one example, QS enables bacteria to restrict the expression of specific genes to the high cell densities at which the resulting phenotypes will be most beneficial.

Examples of use of Quorum sensing
1. How quorum sensing works, and how it evolved, are big topics in biology that are only now being explored in earnest.
2. What the new study shows is that once it kicks in, quorum sensing stimulates the bacteria in biofilms to do more than make slime.
3. While they also made it when they were free–floating, production went way up in the biofilm state, triggered somehow by quorum sensing.
4. Quorum sensing depends on some sort of signaling among bacteria –– although because the organisms have no nervous systems, the signaling is clearly unintentional in the conventional sense.
5. A major insight was that biofilm–based metabolism is triggered by an event called "quorum sensing." Somehow, bacteria are able to detect the presence of other bacteria (usually of the same species) right around them.
