摘要: The structure of softwoods, which confers resistance to degradation through hydrolysis and decay, currently limits their use for the production biofuels. However, since wood is very heterogeneous, it possible that differences in properties within between trees could differentially affect its processability. In this research, heartwood (inner) sapwood (outer) from Norway spruce (Picea abies (L.) Karst.) clones were enzymatically hydrolyzed by Trichoderma viride cellulases after concentrated acid pretreatment. Wood sections with two particle sizes compared based on susceptibility enzymatic hydrolysis, evaluated assaying formation products measured as reducing sugar yield (RSY). We also studied relationship RSY Heterobasidion parviporum decay whether these traits are reflected density yield. outer section produced more higher glucan but lower lignin content than fro...
