Delignification of switchgrass for xylo-oligosaccharides production using sorbic acid hydrolysis

Bioresource Technology, 2023
Organic acid as a class of hydrolysis catalysts shows great potential in the production of xylo-oligosaccharides (XOS) from lignocelluloses. However, sorbic acid (SA) hydrolysis for XOS production from lignocellulose has not been reported and it was still unclear how lignin removal affected XOS production.

Delignification of poplar for xylo-oligosaccharides production using lactic acid catalysis

Bioresource Technology, 2021
Recently, xylo-oligosaccharides (XOS) production from lignocelluloses by organic acid catalysis has been widely reported. However, the effect of delignification of lignocelluloses on XOS production by organic acid catalysis was unclear, and lactic acid (LA) catalysis in XOS production from lignocelluloses has not been reported. In this work, the effect

In Vitro Fermentability of Differently Substituted Xylo-oligosaccharides

Journal of Agricultural and Food Chemistry, 2002
Xylo-oligosaccharides (XOS) with various substituents were fermented in vitro by fecal inocula (FI) from four human volunteers to study the influence of substitution on the ability and rate of fermentation and on the production of short-chain fatty acids (SCFA) and lactate.

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%.

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 ...

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.
