Values represent means ± standard deviations of the three replicates per treatment. The letters (^a, ^b, ^c and ^d) indicate significant difference between treatments at p ≤ 0.05. * and ** indicate significant differences at p ≤ 0.05 and 0.01, respectively. NS means no significant difference at the 0.05 level of probability.
