WebBacteria of the genus Aeromonas display multicellular behaviors herein referred to as “social life”. Since the 1990s, interest has grown in cell-to-cell communication through quorum sensing signals and biofilm formation. As they are interconnected, these two self-organizing systems deserve to be considered together for a fresh perspective on the … WebQuorum sensing has been known to regulate genes involved in various bacterial social behaviors such as biofilm formation, pathogenicity, motility, and antibiotic resistance. It is also associated with the enhancement of biofilm dispersion and upregulation in the synthesis of surfactant molecules. Intuitively, it may even appear to coordinate ...
WebIntroduction Quorum sensing is a cell density dependent mechanism used by bacteria to regulate gene expression. It is an essential component of biofilm physiology, as biofilms have a high concentration of bacterial cells. 1 Quorum sensing or cell to cell communication is utilized by bacteria for biofilm initiation, maturation and dispersal and … WebStill, it exhibited anti-biofilm effects for the late-stage and pre-formed biofilms dispersion.
