Xylan extraction from pretreated sugarcane bagasse using alkaline and enzymatic approaches

open access: yesBiotechnology for Biofuels, 2017
Background New biorefinery concepts are necessary to drive industrial use of lignocellulose biomass components. Xylan recovery before enzymatic hydrolysis of the glucan component is a way to add value to the hemicellulose fraction, which can be used in ...

Designer biomass for next-generation biorefineries: leveraging recent insights into xylan structure and biosynthesis

open access: yesBiotechnology for Biofuels, 2017
Xylans are the most abundant noncellulosic polysaccharides in lignified secondary cell walls of woody dicots and in both primary and secondary cell walls of grasses.

Developing pericarp of maize: a model to study arabinoxylan synthesis and feruloylation

open access: yesFrontiers in Plant Science, 2016
Cell walls are comprised of networks of entangled polymers that differ considerably between species, tissues and developmental stages. The cell walls of grasses, a family that encompasses major crops, contain specific polysaccharide structures such as ...

Conversion of xylan by recyclable spores of Bacillus subtilis displaying thermophilic enzymes

open access: yesMicrobial 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.

Structure of Hardwood Xylan and Specificity ofStreptomyces β-Xylanase toward the Xylan [PDF]

open access: yesBioscience, 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 ...

Hyperthermostable acetyl xylan esterase [PDF]

open access: yesMicrobial Biotechnology, 2009
Summary An esterase which is encoded within a Thermotoga maritima chromosomal gene cluster for xylan degradation and utilization was characterized after heterologous expression of the corresponding gene in Escherichia coli and ...

Efficient Enzymatic Hydrolysis of Biomass Hemicellulose in the Absence of Bulk Water

open access: yesMolecules, 2019
Current enzymatic methods for hemicellulosic biomass depolymerization are solution-based, typically require a harsh chemical pre-treatment of the material and large volumes of water, yet lack in efficiency. In our study, xylanase (E.C.

Acacia Xylan as a Substitute for Commercially Available Xylan and Its Application in the Production of Xylooligosaccharides [PDF]

open access: yesACS 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.
