Cellulase digestibility of pretreated biomass is limited by cellulose accessibility.

TL;DR: Direct evidence is provided to support the notion that the best pretreatment schemes for rendering biomass more digestible to cellobiohydrolase enzymes are those that improve access to the cellulose in biomass cell walls, as well as those able to reduce the crystallinity of cell wall cellulose.
Journal ArticleDOI
Measuring the crystallinity index of cellulose by solid state 13C nuclear magnetic resonance
TL;DR: In this paper, a simple and straightforward method was developed using solid state 13C NMR and subtraction of the spectrum of a standard amorphous cellulose to evaluate the crystallinity index of cellulose.
Journal ArticleDOI
Porosity and Its Effect on the Digestibility of Dilute Sulfuric Acid Pretreated Corn Stover
TL;DR: The goal of this work was to determine if porosity was one of the factors governing the overall enzymatic digestibility of the cellulose in dilute acid pretreated biomass.
Journal ArticleDOI
Can delignification decrease cellulose digestibility in acid pretreated corn stover

TL;DR: The effect of lignin removal on the accessibility and digestibility of dilute acid pretreated corn stover was found to be enhanced in samples with lower xylan contents suggesting that the near complete removal of xylan and lign in may cause aggregation of the cellulose microfibrils resulting in decreased cellulase accessibility.
