Arabinoxylan oligosaccharides (AXOS) are a recently developed group of prebiotics, and already demonstrated a decreasing effect on intestinal generation of

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. A new analytical method that offers structural information was developed to characterize AXOS degradation during fermentation. The method

An extensive lab-scale ball mill treatment (120 h, 50% jar volume capacity) increased the wheat bran water-extractable arabinoxylan (WE-AX) level from 4% (untreated bran) to 61% of the wheat bran AX. Extractable AX 2013-11-01 The arabinoxylan oligosaccharides are excellent tools to map the active site of glycosyl hydrolases involved in xylan deconstruction. The substrate specificities of several xylanases and arabinofuranosidases were determined by analyzing the digestion products after incubation of the oligosaccharides with glycosyl hydrolases. 2015-07-14 The effect of feruloylated arabinoxylan mono- and oligosaccharides (FAXmo) on mammalian α -glucosidase and glucose transporters was investigated using human Caco-2 cells, rat intestinal acetone powder, and Xenopus laevis oocytes. The isolated FAXmo from wheat aleurone and corn bran were identified to have degree of polymerization (DP) of 4 and 1, respectively, by HPLC-MS. 2012-02-01 Enzymatic Polymerization of Arabinoxylan Oligosaccharides Deborah Senf,Colin Ruprecht, Saina Kishani, Aleksandar Matic,Guillermo Toriz, Paul Gatenholm, Lars W,gberg,and Fabian Pfrengle* Abstract: The heterogeneous nature of non-cellulosic poly-saccharides,such as arabinoxylan, makes it difficult to 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.

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.

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.

Villkor: In order to bear the claim 8 g of arabinoxylan-rich fibre produced from Efsa: Isomalto-oligosaccharides are produced by enzymatic hydrolysis of starch

Two pure xylanases namely RmXyn10A from GH family 10 and 3 apr.

They are normally present as glycans : oligosaccharide chains linked to lipids or to compatible amino acid side chains in proteins , by N - or O - glycosidic bonds .

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. The preferred substrates of the purified TrAbf62A were soluble, highly substituted arabinoxylan oligosaccharides and polymers, similar to the type found in barley grain. TrAbf62A exhibited activity towards oligomeric and polymeric arabinoxylans, as well as colorimetric arabinose-based substrates, thus meeting the criteria to be classified as a type B AFase.

A new class of candidate prebiotics is that of the arabinoxylan oligosaccharides (AXOS). AXOS are derived from arabinoxylans, complex carbohydrates found in the cell walls of the starch endosperm and the aleurone layer (Fincher & Stone, 1986) and in pericarp tissues (Maes & Delcour, 2002) of cereals.

An in-depth identiﬁ-cation of acidic (A)XOS oxidation products derived from TEMPO-mediated oxidation provided novel Inulin-type fructans (ITF) and arabinoxylan oligosaccharides (AXOS) are broken down to different extents by various bifidobacterial strains present in the human colon. To date, phenotypic heterogeneity in the consumption of these complex oligosaccharides at the strain level remains poorly studied. To examine mechanistic variations in ITF and AXOS Objectives: We assessed whether wheat bran extract (WBE) containing arabinoxylan-oligosaccharides (AXOS) elicited a prebiotic effect and modulated gastrointestinal (GI) parameters in healthy preadolescent children upon consumption in a beverage. Arabinoxylan oligosaccharides (AXOS) are considered as DF with prebiotic potential, but so far no studies have investigated their metabolic effects in humans.
