Conversion of xylan by recyclable spores of Bacillus subtilis displaying thermophilic enzymes [PDF]
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.

Aggregation of Modified Glucuronoxylan in Water and DMSO. [PDF]
BiopolymersNeutron scattering study of dispersibility of glucuronoxylan and modified glucuronoxylan, in water and dimethyl sulfoxide (DMSO). ABSTRACT Glucuronoxylans are known to be only partly soluble in aqueous media. Chemical modification often aims to improve solubility, yet observations of aggregation even of the modified xylans are not uncommon.

Novel GH115 xylan α-1,2-glucuronidases with distinct preferences for xylan-derived oligomers and polymers. [PDF]
Protein SciAbstract Natural polymers are promising sustainable materials for diverse applications. Xylans, major components of hemicellulose, exhibit origin‐dependent substitution patterns that determine their physicochemical properties. Targeted enzymatic modification of these substituents offers a mild and precise approach for tailoring the polymer's ...

Optimizing yield and chemical compositions of dimethylsulfoxide-extracted birchwood xylan
Journal of Bioresources and Bioproducts, 2022 Dimethylsulfoxide (DMSO) extraction is commonly used to study the chemical structures of original xylan in the plant cell wall, since the DMSO can preserve the original structure of the xylan as much as possible during the extracting process. In addition,
