2.5. Statistical analysis
All experiments and determinations were conducted in triplicates.
Presented results are mean values with standard deviations
(n = 3). The results were also subjected to one-way analysis of variance
(ANOVA) at significance level a = 0.05 using Statistica 10.0
package (StatSoft, Inc., USA). Duncan’s test was used to determine
statistically homogenous groups (denoted as subsequent letters of
the alphabet) and lowest significant differences (LSD).
