Bacteria exchange chemical signals {autoinducer} (AI-1), using special receptors, to determine bacteria density by quorum sensing. Autoinducers help make biofilms, make spores, regulate reproduction, release toxin, and emit light. Autoinducers can exchange boron sugars {autoinducer two} (AI-2) with other species. Gram-negative bacteria use signals {acylated homoserine lactone} (ACL). Gram-positive bacteria use peptide signals.
