Due to their potential prebiotic properties, arabinoxylan-derived oligosaccharides [(A)XOS] are of great interest as functional food and feed ingredients. While the (A)XOS metabolism of Bifidobacteriaceaehas been extensively studied, information regarding lactic acid bacteria (LAB) is still limited in this context.

Feruloylated Arabinoxylan and Oligosaccharides: Chemistry, Nutritional Functions, and Options for Enzymatic Modification Shang Lin , Jane Wittrup Agger , Casper Wilkens , Anne S. Meyer * * Corresponding author for this work The potential of a novel class of prebiotics, arabinoxylan oligosaccharides (AXOS), was investigated on growth performance and gut microbiota of juvenile Acipenser baerii. Two independent feeding trials of 10 or 12 weeks were performed with basal diets supplemented with 2% or 4% AXOS-32-0.30 (trial 1) and 2% AXOS-32-0.30 or AXOS-3-0.25 (trial 2), respectively. Ball milling was used for producing complex arabinoxylan oligosaccharides (AXOS) and low molecular mass arabinoxylans (AX) from wheat bran, pericarp-enriched wheat bran, and psyllium seed husk. The arabinose to xylose ratio of the samples produced varied between 0.14 and 0.92, and their average degree of polymerization (avDP) ranged between 42 and 300. Their fermentation for 48 h in an in Arabinoxylan‐oligosaccharides (AXOS) affect the protein/carbohydrate fermentation balance and microbial population dynamics of the Simulator of Human Intestinal Microbial Ecosystem J. I. Sanchez Laboratory of Microbial Ecology and Technology (LabMET), Ghent University, Coupure Links 653, B‐9000 Gent, Belgium. An arabinose specific xylanase from glycoside hydrolase family 5 (GH5) was used to hydrolyse wheat and rye arabinoxylan, and the product profile showed that it produced arabinose substituted oligosaccharides (AXOS) having 2-10 xylose residues in the main chain but no unsubstituted xylooligosaccharides (XOS). The main products of AX enzymatic hydrolysis are arabinoxylan-oligosaccharides (AXOS) and xylan-oligosaccharides (XOS), which show prebiotic potential because of their ability to increase the abundance of bifidobacteria and some butyrate producers in the gut (14 – 16).

A range of α-L-arabinofuranosyl-(1-4)-β-D-xylo-oligosaccharides (AXOS) were produced by hydrolysis of wheat flour arabinoxylan (WAX) and acid debranched arabinoxylan (ADWAX), in the presence and absence of an AXH-d3 α-L-arabinofuranosidase, by several GH10 and GH11 β-xylanases.

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.

2007-02-01 · Arabinoxylans (AX) are the main non-starch polysaccharides found in many cereal grains and are part of dietary fibre. They consist of β- (1,4)-linked d -xylopyranosyl residues to which arabinofuranosyl moieties are attached. They are degraded in the colon by specific intestinal bacteria possessing AX-degrading enzymes.

Many oligosaccharides exert prebiotic activities and there are indications that xylo-oligosaccharides consisting of β-(1,4)-linked d -xylopyranosyl residues show strong bifidogenic effects. 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.
