Arabinoxylan oligosaccharides

Arabinoxylans are comprised of a mixed linkage between arabinose and xylose. Arabinoxylan-oligosaccharides (AXOS) are a recently newly discovered class of candidate prebiotics as - depending on their structure - they are fermented in different regions of gastrointestinal tract. Arabinoxylan is a dietary fiber found in cereal grains such as wheat, corn, rice, rye, oat, and barley. It is used as a medicine. Arabinoxylan is taken by mouth for heart disease, constipation, Due to their potential prebiotic properties, arabinoxylan-derived oligosaccharides [(A)XOS] are of great interest as functional food and feed ingredients.

Wheat bran arabinoxylan can be converted by enzymatic hydrolysis into short arabinoxylo-oligosaccharides (AXOS) with prebiotic potential. Alkali extraction of arabinoxylan from wheat-bran offers advantages in terms of yield and results in arabinoxylan with highly-substituted regions which has been a challenge to hydrolyse using endoxylanases.

Consumption of breads containing in situ-produced arabinoxylan oligosaccharides alters gastrointestinal effects in healthy volunteers. Research output: Contribution to journal › Article

Many gut microbes are capable of degrading arabinoxylans, such as lactobacilli, Bacteroides, Roseburia eubacterium, Faecalibacterium prausnitzii, Bi. animalis, and nonpathogenic clostridia (Grootaert et al., 2009). 2015-04-07 · To characterize the binding epitopes of these powerful molecular probes a library of eleven plant arabinoxylan oligosaccharides was produced by automated solid-phase synthesis. 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.

3 apr. 2020 — Arabinoxylan oligosaccharides (AXOS) are a prebiotic product that advantageously affect the activity and composition of the gut bacteria.

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.

Helsinki 2020. Arabinoxylan-oligosaccharides (AXOS) are a recently newly discovered class of candidate prebiotics as - depending on their structure - they are fermented in different regions of gastrointestinal tract. This can have an impact on the protein/carbohydrate fermentation balance in the large intestine and, thus, affect the generation of potentially Arabinoxylan oligosaccharides (AXOS) are prebiotic carbohydrates with promising health-promoting properties that stimulate the activity of specific colon bacteria, in particular bifidobacteria.

The first criterion is resistance to gastric acid Herein, a chemoenzymatic approach to artificial arabinoxylan polysaccharides with systematically altered branching patterns is described. The polysaccharides were obtained by glycosynthase‐catalyzed polymerization of glycosyl fluorides derived from arabinoxylan oligosaccharides. 2016-04-21 2012-02-28 Arabinoxylan-oligosaccharides (AXOS) are a new class of prebiotics with promising health-promoting characteristics. However, the mechanism by which bacteria break down these compounds in the colon is still uncharacterized, due to their structural complexity.
