20	11.92 ± 0.53^a	19.00 ± 0.33^a	53.22 ± 0.27^a	65.42 ± 0.44^a
40	37.33 ± 0.57^b	31.51 ± 0.64^b	61.12 ± 0.66^b	69.77 ± 0.58^b
60	41.36 ± 0.31^c	49.05 ± 0.62^c	73.68 ± 0.38^c	74.08 ± 0.38^c
80	55.96 ± 0.54^d	63.25 ± 0.82^d	79.80 ± 0.27^d	79.94 ± 0.17^d
100	76.92 ± 0.53^e	72.79 ± 0.82^e	83.53 ± 0.41^e	84.73 ± 0.38^e

The values are mean of triplicates with (±) standard deviation (mean ± S.D; n = 3). Different superscript letters (a–e) in column within treatments indicates significant differences (at ) when subject to Tukey’s multiple comparison test.
