SEM, standard error of the mean; L, linear trend across fermentation times; q, quadratic trend across fermentation times; NS, non significant.

Different letters in the same row indicate significant differences (**p 0.01; *** p 0.001) between treatments.

Means (Log₁₀ CFU/mL, n = 40) in rows with the same superscript are not significantly different (ns) due to treatment effect.
