Webquorum sensing, mechanism by which bacteria regulate gene expression in accordance with population density through the use of signal molecules. Quorum sensing allows bacteria populations to communicate and coordinate group behaviour and commonly is used by pathogens (disease-causing organisms) in disease and infection processes. Bacterial … WebEPS (containing carbohydrates, lipids proteins) secreted by biofilms provide a quasi-liquid environment for effectively binding PAH and immobilizing metal ions. Various functional moieties, including phosphate, sulfhydryl, carboxylate, amino, and phenolic, impart multiionic character to EPS. Web1.
