  1. Calculated mean is for triplicate measurements from two independent experiments ± SD; means with different superscripts in the same column are considered statistically different (LSD test, P ≤ 0.05)
  2. Different letters on the bars (a, b, c) indicate significant differences between the data points. Bars with the same letter are not significantly different, while bars with different letters are
