AHL-based quorum sensing changes the protein abundance of Salmonella Enteritidis. AHL-based quorum sensing influences the levels of organic acids of Salmonella Enteritidis. The abundance of proteins associated with stationary phase of Salmonella Enteritidis was altered in the presence of AHL. The level of extracellular formate was altered in Salmonella Enteritidis growing in presence of AHL.
