A novel acetyl xylan esterase enabling complete deacetylation of substituted xylans [PDF]
Biotechnology for Biofuels, 2018 Background 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 ...

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 ...

The distribution of Lignin and Xylan in the Inner and Surface Layers of the Fiber from Eucalyptus Kraft Pulp and its Effects on Oxygen Delignification [PDF]
Materials Research, 2017 The chemical structure and composition of lignin and hemicellulose, as well as the distribution between inner and outer layers of fiber, can adversely affect bleaching operations or fiber-fiber bond on pulp and, consequently the papermaking process ...

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,

Preparation of Sulfated Xylans and Its in Vitro Proliferation of Probiotics
Shipin gongye ke-ji, 2023 This study aimed to determine the effect of sulfated xylans on the growth of probiotics. Xylan (Xyl) was chemically modified using the sulfamic acid-N,N-dimethylformamide method to produce sulfated xylan (SXY).

Glycan complexity dictates microbial resource allocation in the large intestine. [PDF]
, 2015 The structure of the human gut microbiota is controlled primarily through the degradation of complex dietary carbohydrates, but the extent to which carbohydrate breakdown products are shared between members of the microbiota is unclear.

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.
