All data were examined in triplicate, and the mean value ± SD was used. Values in the same column with the identical English alphabetical letter are not significantly different () and the value in a and b are significantly difference (P ≤ 0.05), with a confidence limit of 95%. Where: STD: standard deviation, CI_L: confidence interval lower, CI_U: confidence interval upper, N: number, : mean value.
