WebMore recently, it’s become clear that many types of bacteria engage in a mode of cell-cell signaling called quorum sensing. In quorum sensing, bacteria monitor the density of the population (the number of other bacteria in the area) based on chemical signals. When the signaling reaches a threshold level, all the bacteria in the population ... WebBiofilm formation is a highly coordinated process that relies heavily on a cell-density-dependent form of microbial communication called ‘quorum sensing’ (QS). QS is facilitated by the production of small-molecule signals that induce shifts in gene expression and metabolic activity in the organisms residing in and around biofilms.
