WebJan 3, 2024 · Some of the best-known examples of quorum sensing come from studies of bacteria. Bacteria use quorum sensing to coordinate certain behaviors based on the local density of the bacterial population. Bacteria that use quorum sensing constitutively produce and secrete certain signaling molecules (called autoinducers or pheromones).
