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

β-Xylosidase and β-mannosidase in combination improved growth performance and altered microbial profiles in weanling pigs fed a corn-soybean meal-based diet [PDF]
Asian-Australasian Journal of Animal Sciences, 2019 Objective In this study, two glycosidases (XMosidases), β-xylosidase and β-mannosidase, were investigated on their in vitro hydrolysis activities of feed and on the improvement of growth performance in vivo in weanling pigs.

β-Xylosidase Overexpression Alters Pectin and Cellulose Distribution and Modulates Blast Disease Resistance in Rice [PDF]
PlantsPlant cell walls provide structural integrity and defense against biotic and abiotic stresses. In rice (Oryza sativa), xylan is the major hemicellulose, and β-xylosidase hydrolyzes xylan by removing xylose residues from non-reducing ends.

Characterisation of a recombinant β-xylosidase (xylA) from Aspergillus oryzae expressed in Pichia pastoris. [PDF]
AMB Express, 2014 β-xylosidases catalyse the hydrolysis of short chain xylooligosaccharides from their non-reducing ends into xylose. In this study we report the heterologous expression of Aspergillus oryzae β-xylosidase (XylA) in Pichia pastoris under the control of the ...

Improvement of β‐Xylosidase and Endoxylanase Activities in Talaromyces amestolkiae by Genetic Manipulation of the Transcriptional Activator XlnR [PDF]
Microbial BiotechnologyThe ascomycete Talaromyces amestolkiae is a promising source of glycosyl hydrolases for hemicellulose degradation, as it contains a considerably higher number of genes encoding these enzymes than other fungi exploited for plant biomass valorisation.

Effect of Glucose on Endo-xylanase and β-xylosidase Production by Fungi Isolated in Indonesia
Journal of Pure and Applied Microbiology, 2022 Xylanases are widely produced by fungi, and the production of polysaccharide-degrading enzymes, in general, are usually subjected to carbon catabolite repression.

Purification and regulation of the synthesis of a β-xylosidase fromAspergillus nidulans [PDF]
FEMS Microbiology Letters, 1996 β-xylosidase (EC 3.2.1.37) has been purified from Aspergillus nidulans mycelium grown on oat-spelt xylan as sole carbon source. Its pH optimum for activity was found to be 5.0 and the optimum temperature was 50 °C. Its molecular mass was estimated by gel filtration to be 180000.

Purification and biochemical characterization of β-xylosidase fromHumicola griseavar. thermoidea [PDF]
FEMS Microbiology Letters, 1995 β-d-Xylosidase production was maximal for Humicola grisea var. thermoidea grown on xylan as the sole carbon source. The main β-d-xylosidase activity was localised in the periplasm. β-Xylosidase was purified from crude extracts by heat treatment, ammonium sulfate precipitation and chromatography on DEAE-cellulose and Sephadex G-100.

Production of xylose through enzymatic hydrolysis of glucuronoarabinoxylan from brewers’ spent grain
Bioresources and Bioprocessing, 2022 Xylose is an abundant bioresource for obtaining diverse chemicals and added-value products. The production of xylose from green alternatives like enzymatic hydrolysis is an important step in a biorefinery context.
