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.

A novel acetyl xylan esterase enabling complete deacetylation of substituted xylans [PDF]
Biotechnology for Biofuels, 2018 Background Acetylated 4-O-(methyl)glucuronoxylan (GX) is the main hemicellulose in deciduous hardwood, and comprises a β-(1→4)-linked xylopyranosyl (Xylp) backbone substituted by both acetyl groups and α-(1→2)-linked 4-O-methylglucopyranosyluronic acid ...

Outstanding questions on xylan biosynthesis
Plant Science, 2022 Xylan is the second most abundant polysaccharide in plant biomass. It is a crucial component of cell wall structure as well as a significant factor contributing to biomass recalcitrance. Xylan consists of a linear chain of β-1,4-linked xylosyl residues that are often substituted with glycosyl side chains, such as glucuronosyl/methylglucuronosyl and ...

Embedding a feruloyl esterase active site into a thermophilic endoxylanase scaffold for the degradation of feruloylated xylans [PDF]
Computational and Structural Biotechnology JournalThe structural complexity of xylan makes its complete degradation challenging. Strategies to improve its hydrolysis often requires enzyme cocktails with multiple specific activities or proteins harboring multiple catalytic domains.

Producing mixed linked xylooligosaccharides from red algae biomass through single-step enzymatic hydrolysis [PDF]
Biotechnology for Biofuels and BioproductsBackground The red alga Palmaria palmata is a rich source of sugar compounds, particularly mixed-linkage xylans present in the cell walls of the algae. In contrast to their terrestrial lignocellulosic counterparts, these xylans are more easily accessible.

An Update on Xylan Synthesis [PDF]
Molecular Plant, 2012 Plant cell walls are complex structural frameworks that affect cell shape and differentiation, and that protect the plant cell against environmental conditions (Scheller and Ulvskov, 2010). One of the major components of the wall is the hemicellulosic polysaccharide xylan, which is composed of a linear β-(1,4)-linked D-xylosyl (Xyl) backbone with ...
