Figure 1.

Linear relationship between the measured and predicted data for the concentrations of the attached to SS coupons populations (Log₁₀ CFU/cm²) of the four-strain L. monocytogenes cocktail. The mathematical equation of the regression plot, together with its regression coefficient (R²), are also shown. Dots represent the mean values of all experiments included in the CCRD (n = 20; i.e., those shown in Table 1). For more clarity, the bars of standard deviations have been omitted.
