Peptide K6 exhibited higher antibiofilm activity than gentamicin with disruption of an extracellular matrix with nanoparticle structure. (A) Elimination of biofilm formation by Peptide K6 or gentamicin using polystyrene 96-well round-bottom plates. Results were expressed as the biofilm percentage, measured using crystal violet staining. (B) Elimination of biofilm formation by Peptide K6 or gentamicin determined by crystal violet staining using polystyrene round-bottom tubes. (C) Content of an extracellular matrix of established mixed biofilms treated with Peptide K6 or gentamicin. Results were measured using a fluorescence microscope.
