1) NS: Values in a column are not significantly different at p < 0.05
2) a-d: Means with the different superscript in a column are significantly different at p < 0.05
Statistical analysis: The data were expressed as means of triplicate determinations with standard deviation
Analysis of variance (ANOVA) was performed with Duncan’s multiple range test (p < 0.05) using SPSS (ver. 19 for Windows, Chicago, IL, USA)
