nd: not detected. Data presented are in means ± standard deviation (n = 3). Statistical note: Means (n = 3) within a column followed by different letters are significantly different at p < 0.01 according to the Tukey’shonestly significant difference (HSD) multiple range test. * Means with superscripts having the same letter are not significantly different.
