Log reductions (log CFU.cm−2) obtained after P3 treatment [0.5, 1, or 2% (v/v), A, B or C] for 5 or 10 min (A-C) of Listeria monocytogenes biofilms grown at different conditions: TSB-YE, 25°C (
), 1/10 TSB-YE, 25°C (
), TSB-YE, 11°C (
), or 1/10 TSB-YE. 11°C (
). The disinfectant treatment was considered as effective when 4-log reduction in viable bacterial counts was reached. For each culture, different letters in the columns indicate significant differences (p < 0.05). At least two biological replicates were performed, with two technical replicates each.
