Arabinoglucuronoxylan and Arabinoxylan Adsorption onto Regenerated Cellulose Films
… adsorption of arabinoglucuronoxylan (AGX) and arabinoxylan (AX) onto these cellulose surfaces was studied. The effects of structure, molar mass and ionic strength of the solution were considered. Increasing ionic strength increased AGX and AX adsorption onto cellulose. While AGX showed greater …

Nutritional and immunological outcomes as affected by a novel carbohydrate complex composed of galactoglucomannan oligosaccharides and arabinoxylan
… a novel galactoglucomannan oligosaccharide-arabinoxylan (GGMO-AX) complex for properties that could positively impact nutritional and immunological outcomes. Five studies were designed to address three major research objectives: 1) determine the structural and chemical composition of the …

Investigating the impact of colonic bacteroides intestinalis-mediated wheat arabinoxylan degradation on lipid metabolism and inflammation modulation
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2027-08-01

Comparative genome analysis of human bifidobacteria with commercial potential
… of mutants via homologous recombination. Arabinoxylan metabolism by B. longum subsp. longum NCIMB 8809 was investigated in Chapter 4 of this thesis. Transcriptome analysis allowed the identification of a number of genes involved in the degradation, uptake and utilisation of arabinoxylan. …

Polysaccharide utilization by the human colonic bacterium, bacteroides intestinalis DSM 17393
… aim to understand the degradation of esterified arabinoxylan by diverse Bacteroides spp. and to develop a rapid approach for identifying the potential target of a vast number of uncharacterized PULs. Our findings demonstrate that some Bacteroides spp. highly express an esterase-enriched cluster …

Closing the fibre gap in refined cereal product – quality and health
… applied to cake using a broader mix of fibres (arabinoxylan, β-glucan, cellulose, pectin, and RS-IV) which extended shelf life, enhanced nutritional quality, and improved the sensory profile. The optimised cake qualifies as a high-fibre product according to the AOAC 991.43 method, or as a source …

Process-induced changes on the functionality of oat β-glucan evaluated using a gastrointestinal simulation model
… role of other polysaccharides (e.g., starch and arabinoxylan) in gut viscosity enhancement. These findings provide a foundation for future research aimed at optimizing the functional properties of β-glucan in food products.

Regulation of reserve carbohydrates in hull-less barley grain
… from 15 DAP in the mutant grain. Deposition of arabinoxylan, callose and cellulose was altered in the absence of (1,3;1,4)-β-glucan in the mutant endosperm. QPCR analysis identified changes in the expression of starch and fructan biosynthetic genes during the storage phase. At grain maturity, …

[EMBARGOED] Analysis of cereal cyst nematode resistance mechanisms in barley
… with a focus on (1,3;1,4)-β-glucan and arabinoxylan, was surveyed in a selection of susceptible and resistant barley cultivars. The effect of changes in amount of (1,3;1,4)-β-glucan was also examined through infection of the betaglucanless mutant and transgenic lines carrying either the …

Characterization of indigestible fiber in diets based on corn and soybean meal or corn, soybean meal, and distiller dried grains with solubles and in feces from pigs fed these diets
… acids are major barriers to fermentation of arabinoxylans in corn fiber. In Exp. 3, the disappearance of DM in the indigestible fraction of a diet based on corn and SBM and in a diet based on corn, SBM, and DDGS was determined. Both diets were digested without inclusion of enzymes, with …

Comparative whole genome transcriptional responses of Ruminococcus albus strain 7 and 8: a case for specialization and niche differentiation
… acid swollen cellulose (PASC) and wheat arabinoxylan (WAX), this research demonstrated that the top 5 highly expressed glycoside hydrolase (GH) families, including the versatile GH5, GH9 (Cel9B), GH10, GH11, and GH48 (Cel48A), are the primary GH enzymes employed by both strains of R. …
