Effect of MGO on established P. aeruginosa biofilms. P. aeruginosa PAO1 (A) and PA14 (B) biofilms treated with MGO, with and without sugar solution. MGO concentrations used correspond to those in the manuka-type honeys: 100 mg/kg as in manuka-kanuka honey, 700 mg/kg as in MedihoneyM, and 900 mg/kg as in manuka honey. Biofilm formation is expressed as a percentage relative to the untreated control, which is set at 100%. Results presented are mean values from three biological replicates, all performed in triplicate ± SD.
