- Numbers are presented as weight percentages of biomass DM, followed by standard deviations (a and b). The results in each row are grouped according to significance (P <0.05%), where a is significantly higher thanb (similar superscript letters indicate no statistically significant difference). DM, dry matter; HTT, hydrothermal treatment; WSC, water soluble carbohydrates.
