Journal ArticleDOI
Deactivation of cellulases by phenols
TL;DR: Of the phenol molecules tested, tannic acid was the single, most damaging aromatic compound that caused both deactivation and reversible loss (inhibition) of all of enzyme activities tested.
Journal ArticleDOI
Inhibition of cellulases by phenols
TL;DR: This work confirms that the phenols: vanillin, syringaldehyde, trans-cinnamic acid, and hydroxybenzoic acid, inhibit cellulose hydrolysis in wet cake by endo- and exo-cellulases, and cellobiose Hydrolysis by β-glucosidase.
Journal ArticleDOI
Soluble inhibitors/deactivators of cellulase enzymes from lignocellulosic biomass.
TL;DR: In this article, the authors used lignin-free cellulose, Solka Floc, combined with mixtures of soluble components released during pretreatment of wood, to prove that the decrease in the rate and extent of cellulose hydrolysis is due to a combination of enzyme inhibition and deactivation.
Journal ArticleDOI
Composition of corn dry-grind ethanol by-products: DDGS, wet cake, and thin stillage.
Youngmi Kim,Nathan S. Mosier,Rick Hendrickson,Thaddeus Chukwuemeka Ezeji,Hans P. Blaschek,Bruce S. Dien,Michael A. Cotta,Bruce E. Dale,Michael R. Ladisch +8 more
TL;DR: Polymeric sugars, crude protein, crude oil and ash contents of DDGS and wet distillers' grains were accurately and reproducibly determined by the compositional analysis procedure described in this paper.
Journal ArticleDOI
Process and technoeconomic analysis of leading pretreatment technologies for lignocellulosic ethanol production using switchgrass.

TL;DR: The results show limited differentiation between the projected economic performances of the pretreatment options, except for processes that exhibit significantly lower monomer sugar and resulting ethanol yields.
