Anisotropic Transparency of Alkali‐Treated Wood
Macromolecular Materials and EngineeringThis study elucidates the mechanism by which alkali treatment enhances the transparency of delignified wood, with a focus on the cellulose microfibril skeleton. Following delignification, the resulting material remains translucent due to light scattering

Genomics Review of Holocellulose Deconstruction by Aspergilli [PDF]
Microbiology and Molecular Biology Reviews, 2014 SUMMARY Biomass is constructed of dense recalcitrant polymeric materials: proteins, lignin, and holocellulose, a fraction constituting fibrous cellulose wrapped in hemicellulose-pectin. Bacteria and fungi are abundant in soil and forest floors, actively recycling biomass mainly by extracting sugars from holocellulose degradation.
