This file contains additional information, probably added from the digital camera or scanner used to. Abstract. Gram-positive and Gram-negative bacteria use quorum sensing communication circuits to regulate a diverse array of physiological activities. These processes include symbiosis, virulence, competence, conjugation, antibiotic production, motility, sporulation, and biofilm formation. In general, Gram-negative bacteria use acylated homoserine Cited by: Quorum Sensing in Gram-Negative Bacteria The first described quorum-sensing system is that of the bioluminescent marine bac-terium Vibrio fischeri, and it is considered the paradigm for quorum sensing in most gram-negative bacteria (Nealson & Hastings ). .
