In muro deacetylation of xylan affects lignin properties and improves saccharification of aspen wood

Biotechnology for Biofuels, 2017
Background Lignocellulose from fast growing hardwood species is a preferred source of polysaccharides for advanced biofuels and “green” chemicals. However, the extensive acetylation of hardwood xylan hinders lignocellulose saccharification by obstructing

Mutations of Arabidopsis TBL32 and TBL33 Affect Xylan Acetylation and Secondary Wall Deposition. [PDF]

PLoS ONE, 2016
Xylan is a major acetylated polymer in plant lignocellulosic biomass and it can be mono- and di-acetylated at O-2 and O-3 as well as mono-acetylated at O-3 of xylosyl residues that is substituted with glucuronic acid (GlcA) at O-2.

Effect of citric acid on properties of (3-mercaptopropyl)trimethoxysilane modified xylan/polyvinyl alcohol composite film

Cailiao gongcheng, 2023
In order to improved the defects of xylan-based films such as strong hygroscopicity and low mechanical strength, a collaborative modification protocol of citric acid (CA) and MPTMS-modified xylan (MSMX) was proposed.

USING STREPTOMYCES XYLANASE TO PRODUCE XYLOOLIGOSACHARIDE FROM CORNCOB

Biotropia: The Southeast Asian Journal of Tropical Biology, 2011
Streptomyces 234P-16 and SKK1-8 are xylanase-producing bacteria. Corncob xylan were extracted using acidified method. Crude enzymes (produced by centrifuging the culture) were used to hydrolyze xylan from 2 varieties of corncob. Crude extract activity

About the Influence of Doping Approach on the Alkali Metal Catalyzed Slow Pyrolysis of Xylan

Journal of Chemistry, 2019
In this study, we highlighted how the catalytic effect of alkali metals on xylan pyrolysis is strongly affected by the adopted doping approach. Thermogravimetric and pyrolysis tests, up to 973 K and at a heating rate of 7 K/min, were conducted on a set ...
