Each value in the table was obtained by calculating the average of three experiments and data are presented as Mean ± SEM.

Statistical analysis were carried out by Turkeys test at 95% confidence level and statistical significance were accepted at the p < 0.05 level. The superscript letter a, b, c d, e, f denotes the significance of various parameters. Letter a is significant to b, c, d, e, f.
