WebAug 4, 2024 · Biofilms are communities of microorganisms encased in a self-produced matrix constituted of extracellular polymeric substances (EPS). The recalcitrant and often harmful nature of biofilms, particularly in the biomedical field, motivates a search for antibiofilm compounds and materials. 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 ).
