Minimal biofilm eradication concentration 80 (MBEC80) defined as the lowest antimicrobial concentration that prevented at least 80% regrowth of Candida, after the biofilm was treated with antimicrobials for 24 h. MBEC values are in % (v/v) and in brackets are the equivalent MBEC values in (g/L). NA = no antimicrobial activity at tested concentrations.
