Features of promising technologies for pretreatment of lignocellulosic biomass.
Nathan S. Mosier,Charles E. Wyman,Bruce E. Dale,Richard T. Elander,Y. Y. Lee,Mark T. Holtzapple,Michael R. Ladisch +6 more
TL;DR: This paper reviews process parameters and their fundamental modes of action for promising pretreatment methods and concludes that pretreatment processing conditions must be tailored to the specific chemical and structural composition of the various, and variable, sources of lignocellulosic biomass.
Journal ArticleDOI
Coordinated development of leading biomass pretreatment technologies.
Charles E. Wyman,Bruce E. Dale,Richard T. Elander,Mark T. Holtzapple,Michael R. Ladisch,Y. Y. Lee +5 more
TL;DR: Comparative data were developed on sugar recovery from hemicellulose and cellulose by the combined pretreatment and enzymatic hydrolysis operations when applied to corn stover through a Biomass Refining Consortium for Applied Fundamentals and Innovation (CAFI).
Journal ArticleDOI
Fundamental factors affecting biomass enzymatic reactivity.
TL;DR: An empirical model was identified that describes the roles of lignin content, acetyl contents, and crystallinity indices in enzymatic hydrolysis and the digestibility of several lime-treated biomass samples agreed with the empirical model.
Journal ArticleDOI
Comparative sugar recovery data from laboratory scale application of leading pretreatment technologies to corn stover
Charles E. Wyman,Bruce E. Dale,Richard T. Elander,Mark T. Holtzapple,Michael R. Ladisch,Y. Y. Lee +5 more
TL;DR: Overall sugar yields from hemicellulose and cellulose in the coupled pretreatment and enzymatic hydrolysis operations were high and high for all of the pretreatments with corn stover, and high-pH methods were found to offer promise in reducing cellulase use provided hemICEllulase activity can be enhanced.
Journal ArticleDOI
Structural features affecting biomass enzymatic digestibility.
TL;DR: The digestibility results showed that lignin content and biomass crystallinity dominated digestibility whereas acetyl content had a lesser effect andCrystallinity reduction tremendously increased the initial hydrolysis rate and reduced the Hydrolysis time or the amount of enzyme required to attain high digestibility.
