Prairie cordgrass as cellulosic ethanol feedstock and chemical hydrolysis with disk milling for pretreatment
… challenges related to feedstock supply and pretreatment efficiency still exist. To provide sufficient feedstock quantity, eleven natural populations of prairie cordgrass (Spartina pectinata L.) harvested in 2011 and 2012 were evaluated as a bioethanol feedstock. After dilute acid …

High-performance liquid chromatographic methods for quantitative assessment of degradation products and extractives in pretreated lignocellulose.
… for conversion of biomass to ethanol involves dilute acid pretreatment of lignocellulosic materials, followed by enzymatic hydrolysis of cellulose and fermentation of monomeric sugars to produce ethanol. However, a variety of degradation products are produced upon dilute acid pretreatment of …

Genetic Improvement of Switchgrass Cell Wall Content, Leaf Angle and Flowering Time
… plants had uncompromised biomass yield. After dilute acid pretreatment, the low lignin transgenic biomass had significantly increased cellulose hydrolysis (saccharification) efficiency for biofuel production. Erect leaf is a desirable trait to adjust the overall plant architecture to perceive …

Two-stage acidic-alkaline pretreatment of Miscanthus for bioethanol production
Pretreatment is the rate-limiting step for bioethanol production from lignocellulosic biomass, and subsequently intensive studies have been undertaken to improve the pretreatment efficiency. However, so far most pretreatment methods failed to achieve desirable sugar recovery from both cellulose and …

In-situ 13C CM-MAS NMR study of dilute acid biomass pretreatment on 13C enriched poplar wood
… powdered poplar wood that is subjected to pretreatment with water and 0.5 M sulfuric acid as a function of time at 150 °C. 13C MAS (magic-angle spinning) spectra were obtained in both the CP (cross polarization) and DP (direct polarization) modes, the contrasts in this combination yielding …

Compounds Released from Biomass Deconstruction: Understanding Their Effect on Cellulose Enzyme Hydrolysis and Their Biological Activity
… effect of compounds produced during biomass pretreatment on cellulolytic enzyme was investigated. Liquid prehydrolyzates were prepared by pretreating switchgrass using 24 combinations of temperature, time, and sulfuric acid concentration based on a full factorial design. Temperature was …
