Adsorption of Xylan onto Cellulose Fibers Pretreated with Cationic Polyelectrolyte and Its Effect on Paper Properties

BioResources, 2014
Xylan is known as a strength-enhancing agent for paper. However, it is difficult to adsorb xylan onto cellulose fibers because it carries the same negative charge as fibers. Therefore, either cationization of xylan or addition of cationic polyelectrolyte

Synergistic mechanism of GH11 xylanases with different action modes from Aspergillus niger An76

Biotechnology for Biofuels, 2021
Background Xylan is the most abundant hemicellulose polysaccharide in nature, which can be converted into high value-added products. However, its recalcitrance to breakdown requires the synergistic action of multiple enzymes.

Optimizing yield and chemical compositions of dimethylsulfoxide-extracted birchwood xylan

Journal of Bioresources and Bioproducts, 2022
Dimethylsulfoxide (DMSO) extraction is commonly used to study the chemical structures of original xylan in the plant cell wall, since the DMSO can preserve the original structure of the xylan as much as possible during the extracting process. In addition,

Hemicellulose hydrolysis catalysed by solid acids [PDF]

, 2013
Depolymerising hemicellulose into platform sugar molecules is a key step in developing the concept of an integrated biorefinery. This reaction is traditionally catalysed by either enzymes or homogeneous mineral acids.
