Percentages for H, G and S monomers, and S/G ratios. All measurements were repeated three times. One-way ANOVA (followed by Tukey test) was used to determine significant differences for G%, S% and S/G ratios at P < 0.05. Samples with significant statistic difference are labelled with different letters
