Each value is expressed as the mean ± standard deviation (n = 3) of a triplicate analysis. The means followed by different superscripted lowercase letters indicate significant differences () within the rows and columns based on ANOVA two-way factorial test. Small letters represent comparison among interaction means, and capital letters are used for the overall mean. ND: not determined.
