Only radical depolymerization process was allowed to obtain arabinoxylan-oligosaccharides presenting different molecular weights (11.9 x 10(3) to 1.9 x 10(3) g mol(-1)) with satisfactory yields (75% to 35%). PMID: 19888729 2020-01-01 · Dietary fiber such as wheat bran extract (WBE) is enriched in arabinoxylan oligosaccharides (AXOS), which are conceived as prebiotics given their ability to stimulate the growth of bifidobacteria. The AXOS breakdown to arabinose and xylose monomers occurs through the activity of microbes such as Bifidobacterium species. 2018-03-07 · OBJECTIVE AND DESIGN: The aim of this study was to determine the corrective effects of wheat bran-derived arabinoxylan oligosaccharides in obese mice fed a western diet (WD). WD was given for 4 weeks before wheat bran extract (WBE) supplementation (5%) for an additional 4 weeks, whereas a control group received the standard diet. 2015-04-30 · A procedure for the production of A 3 X by hydrolysis of wheat flour arabinoxylan by a GH family 10 endo-1,4-β-xylanase from Aspergillus aculeatus was more recently described by Rantanen et al.

Modular assembly of oligoarabinoxylans from few building blocks was enabled by adding (2-naphthyl)methyl (Nap) to the toolbox of orthogonal protecting groups for solid-phase synthesis. Moreover, the pentasaccharide 33-α-L-arabinofuranosyl-xylotetraose (XA3XX) was found as a highly active DAMP structure triggering strong immune responses in Arabidopsis thaliana and enhancing crop 2009-12-09 · Both chemical and enzymatic treatments were inefficient to convert arabinoxylans from flaxseed mucilage into AXOS. Only radical depolymerization process was allowed to obtain arabinoxylan-oligosaccharides presenting different molecular weights (11.9 x 10(3) to 1.9 x 10(3) g mol(-1)) with satisfactory yields (75% to 35%).

Arabinoxylan-oligosaccharides (AXOS) are produced by partial enzymic hydrolysis of the cereal fibre arabinoxylan (AX) and have recently been proposed as a new prebiotic substrate (Reference Grootaert, Delcour and Courtin 1).To classify a food component as a prebiotic, it needs to fulfil three criteria (Reference Gibson, Probert and Van Loo 2).. The first criterion is resistance to gastric acid Herein, a chemoenzymatic approach to artificial arabinoxylan polysaccharides with systematically altered branching patterns is described.

The arabinoxylan polysaccharides consist of a backbone of β-(1→4)-linked xylopyranosyl residues, which carry arabinofuranosyl moieties, hence the term arabinoxylan. 2012-02-01 2013-09-01 Arabinoxylans (AX) from cereals are cell wall components that constitute an important part of the dietary fiber intake in humans. Enzymatic hydrolysis of AX yields arabinoxylan-oligosaccharides (AXOS), consisting of arabinoxylooligosaccharides and xylooligosaccharides (XOS).
