Abstract
Lignocellulose has been considered as one of the most promising biomass feedstock for producing biofuels and biochemicals. However, lignocellulose is indeed a complicated natural biomaterial at nano- and microscales. This is because the chemical compositions of lignocellulose cell wall construct a bulwark with a spatially hierarchy nano- and ultrastructure to protect the structural carbohydrates from degradation, which is known as the biomass recalcitrance. In this chapter, we have reviewed the structural features of lignocellulosic biomass, particularly on the hierarchy nano- and ultrastructure of plant cell wall and its impact on the bioconversion of the biomass. The effects of various pretreatments on the structure changes of the biomass substrates have been discussed. The tools and methodologies to characterize the nano- and ultrastructure of lignocellulosic biomass also have been reviewed.
