Biochemical Basis of Xylooligosaccharide Utilisation by Gut Bacteria

International Journal of Molecular Sciences, 2022
Xylan is one of the major structural components of the plant cell wall. Xylan present in the human diet reaches the large intestine undigested and becomes a substrate to species of the gut microbiota. Here, we characterised the capacity of Limosilactobacillus reuteri and Blautia producta strains to utilise xylan derivatives. We showed that L.

Miscanthus×giganteus xylooligosaccharides: Purification and fermentation [PDF]

Carbohydrate Polymers, 2016
A procedure was developed to recover xylooligosaccharides (XOS) from Miscanthus×giganteus (M×G) hydrolyzate. M×G hydrolyzate was prepared using autohydrolysis, and XOS rich fractions were acquired using activated carbon adsorption and stepwise ethanol elution. The combined XOS fractions were purified using a series of ion exchange resin treatments. The

Co-production of Xylooligosaccharides and Xylose From Poplar Sawdust by Recombinant Endo-1,4-β-Xylanase and β-Xylosidase Mixture Hydrolysis

Frontiers in Bioengineering and Biotechnology, 2021
As is well-known, endo-1,4-β-xylanase and β-xylosidase are the rate-limiting enzymes in the degradation of xylan (the major hemicellulosic component), main functions of which are cleavaging xylan to release xylooligosaccharides (XOS) and xylose that ...

Biochemical and kinetic characterisation of a novel xylooligosaccharide-upregulated GH43 β-d-xylosidase/α-l-arabinofuranosidase (BXA43) from the probiotic Bifidobacterium animalis subsp. lactis BB-12 [PDF]

, 2013
The Bifidobacterium animalis subsp. lactis BB-12 gene BIF_00092, assigned to encode a β-d-xylosidase (BXA43) of glycoside hydrolase family 43 (GH43), was cloned with a C-terminal His-tag and expressed in Escherichia coli.

Immunomodulatory Effects of Xylooligosaccharides

Food Science and Technology Research, 2012
Xylooligosaccharides (XOs) are considered as food ingredients, and exhibit the prebiotic effects related to gut modulation. However, no related research is available to explain their immunomodulatory effects. This report elucidated their immunomodulatory effects through the variations of proinflammatory mediators in vitro. We found that XOs (0.1-100 mu
