Standard deviations obtained from triplicate experiments in parentheses. N0, initial microbial population; 4Dr, time for a reduction of 4 log10 from N0;kmax, maximum death rate. Values followed by different superscript letters, within the same row, are significantly different according to the Scheffé posthoc comparison test.
