Biofilm activity
WebOxygen scarcity and little metabolic activity in biofilms provide P. aeruginosa greater tolerance to many antibiotics ( Wilkins et al., 2014 ). Sudden changes in pH between layers in a biofilm play a role to accumulate organic acids, thus deactivating the penetrating compounds ( Wilkins et al., 2014 ).

Biofilms are ubiquitous in organic life. Nearly every species of microorganism have mechanisms by which they can adhere to surfaces and to each other. Biofilms will form on virtually every non-shedding surface in non-sterile aqueous or humid environments. Biofilms can grow in the most extreme environments: from, for example, the extremely hot, briny waters of hot springs ranging from v… WebA disturbed balance within the dental biofilm can result in the dominance of cariogenic and periodontopathogenic species and disease development.
