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%). 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 present invention related to an arabinoxylo-oligosaccharide composition comprising Arabinoxylan-oligosaccharides (A)XOS comprises a mixture of both

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.
