Laboratory Evolution of GH11 Endoxylanase Through DNA Shuffling: Effects of Distal Residue Substitution on Catalytic Activity and Active Site Architecture

Frontiers in Bioengineering and Biotechnology, 2019
Endoxylanase with high specific activity, thermostability, and broad pH adaptability is in huge demand. The mutant library of GH11 endoxylanase was constructed via DNA shuffling by using the catalytic domain of Bacillus amyloliquefaciens xylanase A (BaxA)

Integrated bioprocess approach for the production of xylooligosaccharides [PDF]

, 2019
The demand of prebiotic ingredients has been growing over the years as consumers pay more attention to their health. Xylooligosaccharides (XOS) are considered emergent and competitively priced prebiotics, presenting high potential as food ingredients. As

Screening of Xylanolytic Aspergillus fumigatus for Prebiotic Xylooligosaccharide Production Using Bagasse

Food Technology and Biotechnology, 2015
Sugarcane bagasse is an important lignocellulosic material studied for the production of xylooligosaccharides (XOS). Some XOS are considered soluble dietary fibre, with low caloric value and prebiotic effect, but they are expensive and not easily ...

The glycoside hydrolase family 8 reducing-end xylose-releasing exo-oligoxylanase Rex8A from Paenibacillus barcinonensis BP-23 is active on branched xylooligosaccharides

, 2018
A GH8 family enzyme involved in xylan depolymerization has been characterized. The enzyme, Rex8A, is a reducing-end xylosereleasing exo-oligoxylanase (Rex) that efficiently hydrolyzes xylooligosaccharides and shows minor activity on polymeric xylan ...

A novel acid-tolerant β-xylanase from Scytalidium candidum 3C for the synthesis of o-nitrophenyl xylooligosaccharides

, 2020
Endo-β-xylanases are hemicellulases involved in the conversion of xylans in plant biomass. Here, we report a novel acidophilic β-xylanase (ScXynA) with high transglycosylation abilities that was isolated from the filamentous fungus Scytalidium candidum ...

Enzymatic synthesis of capsaicin 4-O-β-xylooligosaccharides by β-xylosidase from Aspergillus sp.

Capsaicin 4-O-β-xylooligosaccharides were synthesized by a biocatalytic xylosylation using Aspergillus sp. β-xylosidase. Capsaicin was converted into three new capsaicin glycosides, i.e.

Preparation of a robust immobilized biocatalyst of β-1,4-endoxylanase by surface coating with polymers for production of xylooligosaccharides from different xylan sources

, 2018
Xylooligosaccharides display interesting prebiotic effects on human health. The endoxylanase Xys1Δ, from Streptomyces halstedii JM8, was immobilized and stabilized on glyoxyl-agarose beads by multipoint covalent attachment using a novel strategy based on
