The arabinoxylan polysaccharides consist of a backbone of β-(1→4)-linked xylopyranosyl residues, which carry arabinofuranosyl moieties, hence the term arabinoxylan.
Rye bran was heat pretreated to improve xylanase-catalyzed hydrolysis of arabinoxylan into arabinoxylan-oligosaccharides. | Pure arabinoxylan (AX) oligosaccharides trigger early immune responses in Arabidopsis. 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. AX depolymerization products obtained by endo-xylanase (EC 3.2.1.8)-catalyzed hydrolysis are denoted arabinoxylan-oligosaccharides.Following previously described criteria (), the present paper uses the following acronyms: XOS for xylooligosaccharides, AXOS for arabino-xylooligosaccharides, (A)XOS for mixtures of XOS and AXOS, and (A)XOS as well for unspecified products of AX depolymerization. Arabinoxylan is a dietary fiber found in cereal grains such as wheat, corn, rice, rye, oat, and barley. It is used as a medicine.
The polysaccharides were obtained by glycosynthase‐catalyzed polymerization of glycosyl fluorides derived from arabinoxylan oligosaccharides. 2016-04-21 · Interestingly, when arabinoxylan oligosaccharides (AXOS), which has prebiotic characteristics as summarized by Broekaert et al.

The aim was to study arabinoxylan-oligosaccharide production from rye bran using heat pretreatment and enzymatic hydrolysis. Due to the potential application in foods, the purity of arabinoxylan was also assessed.
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%).
