Total 63 sweet sorghum accessions are detected with diverse
soluble sugar and dry bagasse levels, and both sugar and bagasse
products are also examined without significant impact on lignocellulose
digestibility. However, either DP of cellulose or Ara substitution
degree of non-KOH-extractable hemicelluloses largely affects
lignocellulose crystallinity (CrI) for high biomass saccharification
upon various NaOH and H2SO4 pretreatments. In addition,
G-monomer could determine lignin negative effect on biomass
enzymatic saccharification and has significant inhibition to yeast
fermentation towards ethanol production. Hence, this study can
suggest the potential genetic modification of plant cell walls for
high biofuels in sweet sorghum.
