WebMar 14, 2024 · Biofilm formation in cooling water systems poses a public health risk associated with the presence there of pathogens. Biofilms can favour the presence, survival and proliferation of thermotolerant pathogenic bacteria, especially Legionella pneumophila, held responsible for about 90% of worldwide cases of Legionnaires' disease (Wéry et al. 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 … WebThe formation of biofilms is a complex process and is dependent upon the availability of light as well as the relationships between the microorganisms. Biofilms serve a variety of roles in aquatic, terrestrial, and extreme environments; these roles include functions which are both beneficial and detrimental to the environment. highlander xle awd
