Effect of structural features on enzyme digestibility of corn stover.
Sehoon Kim,Mark T. Holtzapple +1 more
TL;DR: The enzymatic digestibility of lime-treated corn stover was affected by the change of structural features (acetylation, lignification, and crystallization) resulting from the treatment, and the degree of crystallinity slightly increased from 43% to 60% with delignification because amorphous components (lignin, hemicellulose) were removed, but the increased crystallinity did not negatively affect the 3-d sugar yield of enzymatics.
