Panicum virgatum; digestibility; fuels; glucans; glucose; sulfuric acid; temperature; xylose
Abstract:
... Pretreatment is an important unit operation in the production of cellulosic fuels because it governs the efficiency of the overall conversion process. The effect of dilute acid pretreatment parameters on prehydrolyzate xylose and glucose concentrations, as well as on glucan content and digestibility of pretreated switchgrass, was determined using a full factorial design. Temperature varied from 14 ...

Abstract:
... Pinewood is an abundant source of lignocellulosic biomass that has potential to be used as renewable feedstock in biorefineries for conversion into advanced biofuels and other value-added chemicals. However, its structural recalcitrance, due to the compact packing of its major components, viz. cellulose, hemicellulose and lignin, high lignin content, and high cellulose crystallinity, is a major bo ...

Panicum virgatum; beta-glucosidase; biomass; cellulose; endo-1,4-beta-glucanase; enzyme activity; enzyme inhibition; enzyme inhibitors; hydrolysates; hydrolysis; models; polyphenols; saccharification; statistical analysis; sulfuric acid; temperature
Abstract:
... The identification of biomass pretreatment-generated compounds that impede cellulose hydrolysis is critical for improving the overall biomass saccharification process. The aim of this study was to correlate the identification and concentrations of switchgrass dilute acid pretreatment-generated compounds to cellulolytic enzyme inhibition and to tie this back to processing parameters. Preparation of ...
