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 ).
