The Physical Basis of Bacterial Quorum Communication
Many bacterial species engage in the behavior known as quorum sensing (QS), which can be described as the regulation of gene expression in response to changes in the bacterial population density [1]. The bacteria synthesize and release diffusible small molecules known as autoinducers, which accum...

| description |
Many bacterial species engage in the behavior known as quorum sensing (QS),
which can be described as the regulation of gene expression in response to changes
in the bacterial population density [1]. The bacteria synthesize and release diffusible
small molecules known as autoinducers, which accumulate in the environment.
When the concentration of autoinducer (AI) reaches a threshold level, indicating the
presence of a “quorum” of cells, the population responds as a whole by activating
certain gene regulatory networks, leading to colony-wide changes in phenotype.
A wide range of bacterial behaviors are now known to be regulated through
QS. These include biofilm production, genetic competence, bioluminescence, vari
ous types of motility, and the production of exoenzymes, toxins, bacteriocins, and
other types of virulence factors and secreted products. As the collective production
and detection of the autoinducer signal allows the entire population to synchronize
gene regulation, quorum sensing (QS) is a form of chemical communication and a
social behavior. Accordingly it has attracted tremendous interest from researchers
in many fields... |
