Purification of xylo-oligosaccharides from almond shells by ultrafiltration

Separation and Purification Technology, 2007
Abstract Ultrafiltration using commercial thin-film polymeric membranes was studied to purify the xylo-oligosaccharides (XOs) obtained by autohydrolysis of almond shells. Almond shells are agricultural residues with a high content of xylan that are produced abundantly in some regions with Mediterranean climate.

Xylo-oligosaccharides inhibit pathogen adhesion to enterocytes in vitro

Research in Microbiology, 2012
We previously reported that the non-digestible carbohydrates inulin and apple pectin promoted Listeria monocytogenes infection in guinea pigs, whereas xylo- and galacto-oligosaccharides (XOS and GOS), prevented infection by this pathogen. In the present study, mechanisms that could explain the previous in vivo observations were explored.

Dietary xylo-oligosaccharide improves intestinal functions in weaned piglets

Food & Function, 2019
This study aimed at investigating the effects of dietary xylo-oligosaccharide (XOS) on intestinal functions (i.e., intestinal morphology, tight junctions, gut microbiota and metabolism) and growth performance in weaned piglets.

Structural characterization of xylo-oligosaccharides from corncob residues

Journal of Carbohydrate Chemistry, 2016
The structure of xylo-oligosaccharides (XOSs) derived from corncob residues was elucidated by means of FT-IR, GC-MS, ESI-CID-MS/MS, and 2D-NMR.

Green approach to produce xylo-oligosaccharides and glucose by mechanical-hydrothermal pretreatment

Bioresource Technology, 2022
A pretreatment method combining ball-milling, ultrasound, and hydrothermal treatment was developed to produce xylooligosaccharides (XOS) and glucose with a high yield from corn stover. Under optimal conditions, the yield of XOS reached 80.40%, and the functional XOS (X2-X4) took up to 26.97%.

Xylo-oligosaccharides enriched yeast protein feed production from reed sawdust

Bioresource Technology, 2018
The aim of this study was to convert the cellulose and hemicellulose, in reed sawdust from the pulp mills, into yeast protein and xylo-oligosaccharide, then functionalize xylo-oligosaccharide as yeast feed. Both synchronous saccharification and fermentation and separate hydrolysis and fermentation of cellulase and Candida utilis were investigated to ...

Improving xylo-oligosaccharides yield from corn stalk with stepwise enzymolysis

Biomass Conversion and Biorefinery, 2021
Valorization of renewable carbon sources such as lignocellulosic biomass (LCB) or agricultural residues to produce value-added bioproducts has attracted increasing attention. In this way, a sustainable and abundantly present biopolymer xylan can be utilized to produce xylo-oligosaccharide (XOS) which has potential benefits for individuals and the ...

Autohydrolysis of agricultural by-products for the production of xylo-oligosaccharides [PDF]

Carbohydrate Polymers, 2007
Six agricultural residues of different botanic origin, namely corncobs (CC), almond shells (AS), olive stones (OS), rice husks (RH), wheat straw (WS), and barley straw (BS), were tested as feedstocks for the production of xylo-oligosaccharides (XOs) by autohydrolysis at 179 °C for 23 min.

Xylo-oligosaccharides are competitive inhibitors of cellobiohydrolase I from Thermoascus aurantiacus

Bioresource Technology, 2012
The effects of xylo-oligosaccharides (XOS) and xylose on the hydrolytic activities of cellulases, endoglucanase II (EGII, originating from Thermoascus aurantiacus), cellobiohydrolase I (CBHI, from T. aurantiacus), and cellobiohydrolase II (CBHII, from Trichoderma reesei) on Avicel and nanocellulose were investigated.
