Tuning Xylan Polymerisation Enhanced Fibre Digestibility Without Biomass Loss in Sheepgrass (Leymus chinensis). [PDF]

Plant Biotechnol J
ABSTRACT Leymus chinensis (sheepgrass), a dominant perennial grass of the Eurasian Steppe, is a crucial source of carbohydrates and energy for ruminants. However, the lignocellulose recalcitrance severely limits its digestibility. Here, we targeted xylan, a major hemicellulose interacting with cellulose and lignin in cell wall. To improve digestibility,

The Xylan of Rhodymenia palmata [PDF]

Nature, 1950
Barry and Dillon1 reported the isolation from the red seaweed Rhodymenia palmata of a polysaccharide which gave D-xylose on hydrolysis. Our special interest in xylans2 has led us to investigate this substance more fully as part of the research programme of the Scottish Seaweed Research Association.

An Update on Xylan Synthesis [PDF]

Molecular Plant, 2012
Plant cell walls are complex structural frameworks that affect cell shape and differentiation, and that protect the plant cell against environmental conditions (Scheller and Ulvskov, 2010). One of the major components of the wall is the hemicellulosic polysaccharide xylan, which is composed of a linear β-(1,4)-linked D-xylosyl (Xyl) backbone with ...

Alterations of the degree of xylan acetylation inArabidopsisxylan mutants [PDF]

Plant Signaling & Behavior, 2014
Xylan is the second most abundant polysaccharide in secondary walls of dicot plants and one of its structural features is the high degree of acetylation of xylosyl residues. In Arabidopsis, about 60% of xylosyl residues in xylan are acetylated and the biochemical mechanisms controlling xylan acetylation are largely unknown.

A novel acetyl xylan esterase enabling complete deacetylation of substituted xylans [PDF]

Biotechnology for Biofuels, 2018
Acetylated 4-O-(methyl)glucuronoxylan (GX) is the main hemicellulose in deciduous hardwood, and comprises a β-(1→4)-linked xylopyranosyl (Xylp) backbone substituted by both acetyl groups and α-(1→2)-linked 4-O-methylglucopyranosyluronic acid (MeGlcpA).

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,

Extraction of sugarcane bagasse arabinoxylan, integrated with enzymatic production of xylo-oligosaccharides and separation of cellulose

Biotechnology for Biofuels, 2021
Sugarcane processing roughly generates 54 million tonnes sugarcane bagasse (SCB)/year, making SCB an important material for upgrading to value-added molecules.

Structure of Hardwood Xylan and Specificity ofStreptomyces β-Xylanase toward the Xylan [PDF]

Bioscience, Biotechnology, and Biochemistry, 1994
Three kinds of xylo-oligosaccharides having structures of 3(2)-beta-xylosylxylobiose, 3(2)-beta-xylobiosylxylobiose, and 2(2)-beta-xylobiosyl-xylobiose were isolated from an enzymatic hydrolysate of hardwood xylan with Streptomyces beta-xylanase. The structures suggest that the hardwood xylan has both (1-->2)- and (1-->3)-beta-D-xylopyranosyl linkages ...
