Figure 2

Box and whiskers plots of the parameter estimated for the Gompertz equation of the pH drop curves of strains in relation to the isolation source and NaCl concentration. Boxes represent the limit of the 25th and 75th percentile of the distribution, the line inside the boxes represents the median and the whiskers represent the minimum and maximum values. (a) Maximum pH reduction estimates; (b) Maximum pH decrease rate estimates (ΔpH/h); (c) lag (h) to detect a measurable pH drop. Blue = Salame Romagnolo, Red = Salame Bresciano, Green = Salame Basilicata.
