Enzymatic accessibility of xylans in lignocellulosic materials [PDF]
, 1994 The hydrolysis of fibre-bound and isolated xylans from both birch and pine wood and kraft pulps was studied using purified xylanolytic enzymes of Trichoderma reesei.

Structure of Hardwood Xylan and Specificity ofStreptomyces β-Xylanase toward the Xylan [PDF]
Bioscience, Biotechnology, and Biochemistry, 1994 Three kinds of xylo-oligosaccharides having structures of 3(2)-beta-xylosylxylobiose, 3(2)-beta-xylobiosylxylobiose, and 2(2)-beta-xylobiosyl-xylobiose were isolated from an enzymatic hydrolysate of hardwood xylan with Streptomyces beta-xylanase. The structures suggest that the hardwood xylan has both (1-->2)- and (1-->3)-beta-D-xylopyranosyl linkages ...

Conversion of xylan by recyclable spores of Bacillus subtilis displaying thermophilic enzymes
Microbial Cell Factories, 2017 Background The Bacillus subtilis spore has long been used to display antigens and enzymes. Spore display can be accomplished by a recombinant and a non-recombinant approach, with the latter proved more efficient than the recombinant one.

Insights into Adsorption Characterization of Sulfated Xylans onto Poly(ethylene terephthalate) [PDF]
, 2020 The main aim of this investigation was to study the interaction of sulfated xylans as antithrombotic substances with poly(ethylene terephthalate) (PET) model films as a model for blood contacting surfaces. The adsorption of sulfated xylans onto PET model

Acacia Xylan as a Substitute for Commercially Available Xylan and Its Application in the Production of Xylooligosaccharides [PDF]
ACS Omega, 2020 Over the past two decades, birchwood and beechwood xylans have been used as a popular substrate for the characterization of xylanases. Recently, major companies have discontinued their commercial production. Therefore, there is a need to find an alternative to these substrates. Xylan extraction from Acacia sawdust resulted in 23.5% (w/w) yield.
