Values represent mean ± SD (n = 3). Different letters in the same column indicate statistical differences (p < 0.05) between samples by Scott-Knott post-hoc test. The Shapiro-Wilk test was used to determinate the normal distribution of the data; and the Box-Cox transformation factor (λ), for nonparametric data.
