^a Defined as described in the experimental section; data are presented as the average ± standard deviation (n = 3); ^b pH values are the average of data from the 3rd to 15th day of sampling (n = 15); ND refers to exponential growth not detected by regression analysis (R² < 0.95); in these cases, growth rate was calculated from day 0 to 15; Significant differences are reported in comparison to the control: * Dunn test, p < 0.05; ** Dunn test, p < 0.01.
