The materials were tested against both Gram-negative (Escherichia coli and Salmonella Typhimurium) and Gram-positive (Listeria monocytogenes) bacteria. Minimal inhibitory and maximal tolerated concentrations of the quaternary ammonium monomers were first determined. Films of pure quaternary ammonium functionalized polymers (QAFPs) and of blends of QAFPs with commercial matrices were studied to determine their inhibition effects and their bactericidal activity. A high antibacterial activity was found, up to 5.6 log, 4.4 log, and 4.2 log CFU.mL-1 reduction for respectively Escherichia coli (Salmonella Typhimurium and Listeria monocytogenes after only one hour of bactericidal tests, 6.7 log, 5.2 log and 4.9 log CFU.mL−1 reduction was observed for the respectively cited bacteria after 24 h, making these materials potentially applicable in many fields.Lire moins >
