Quorum sensing, mechanism by which bacteria regulate gene expression in accordance with population density through the use of signal molecules. Quorum sensing allows bacteria populations to communicate and coordinate group behaviour and commonly is used by pathogens (disease-causing organisms) in disease and infection processes Quorum sensing is a system of stimulus and response correlated to population density. Many species of bacteria use quorum sensing to coordinate gene expression according to the density of their local population. In similar fashion, some social insects use quorum sensing to determine where to nest. In addition to its function in biological systems, quorum sensing has several useful applications for computing and robotics. Quorum sensing can function as a decision-making process in any Quorum sensing allows us to learn about signal transduction, gene regulation, cell–cell communication, and collective behaviors, all general properties of life. Bacteria in different microbomes talk to one another by sensing secreted chemicals, a process known as quorum sensing. Quorum sensing turns on group behaviors which allow bacteria to form biofilms or cause diseases such as cholera Quorum sensing (QS) is a form of cell-to-cell signaling in bacteria, which regulates the expression of genes and QS-controlled phenotypes in a population-dependent manner. QS involves the production of small diffusible signaling molecules that are released into the surrounding environment. These are taken up actively or passively by neighboring cells where they have two major consequences. First, the uptake of signal molecules stimulates the production and release of a number of QS-regulated Quorum sensing is a process of cell-to-cell communication by which individual cells regulate their phenotype in response to the extracellular concentration of small molecules. This is achieved by the secretion of small molecules into the environment that bind sensory proteins and directly or indirectly affect transcription and translation. This process, termed quorum sensing, allows bacteria to monitor the environment for other bacteria and to alter behavior on a population-wide scale in response to changes in the number and/or species present in a community. Quorum sensing is the regulation of gene expression in response to fluctuations in cell-population density. Quorum sensing bacteria produce and release chemical signal molecules called autoinducers that increase in concentration as a function of cell density. The detection of a minimal threshold stimulatory concentration of an autoinducer leads to an alteration in gene expression. Gram-positive and Gram-negative bacteria use quorum sensing communication circuits to regulate a diverse array
