摘要: Abstract Hydrothermal pretreatment was performed on the leaves and internodes portions of Alamo switchgrass, Panicum virgatum L., to enhance digestibility cellulose towards cellulase. It observed that extractives free portion provided 18.1% lower gravimetrical yield 33.8% greater cellulose-to-glucose than portion. The degree polymerization (DP) ultrastructure were determined by gel-permeation chromatography solid-state cross polarization/magic angle spinning 13 C NMR experiments. results suggested hydrothermal hydrolyzed amorphous yielded a product enriched in paracrystalline cellulose. Furthermore, DP reduced one third origin value after pretreatment. resulting biomass for has similar chemical profiles. enzymatic hydrolysis studies suggest pretreated switchgrass an important factor influencing enhanced switchgrass.
