Effect of Oligosaccharide Degree of Polymerization on the Induction of Xylan-Degrading Enzymes by Fusarium oxysporum f. sp. Lycopersici

Molecules, 2020
Xylan is one of the most abundant carbohydrates on Earth. Complete degradation of xylan is achieved by the collaborative action of endo-β-1,4-xylanases and β-d-xylosidases and a number of accessories enzymes.

Use of xylosidase 3C from Segatella baroniae to discriminate xylan non-reducing terminus substitution characteristics [PDF]

BMC Research Notes
Objective New characterized carbohydrate-active enzymes are needed for use as tools to discriminate complex carbohydrate structural features. Fungal glycoside hydrolase family 3 (GH3) β-xylosidases have been shown to be useful for the structural ...

Improvement of β‐Xylosidase and Endoxylanase Activities in Talaromyces amestolkiae by Genetic Manipulation of the Transcriptional Activator XlnR [PDF]

Microbial Biotechnology
The ascomycete Talaromyces amestolkiae is a promising source of glycosyl hydrolases for hemicellulose degradation, as it contains a considerably higher number of genes encoding these enzymes than other fungi exploited for plant biomass valorisation.

Heterologous Expression of a New Acetyl Xylan Esterase from Aspergillus niger BE-2 and its Synergistic Action with Xylan-Degrading Enzymes in the Hydrolysis of Bamboo Biomass

BioResources, 2016
Efficient utilization of plant biomass by enzymatic hydrolysis is currently studied worldwide but still faces enormous challenges because of the inability to break down lignocellulosic materials with high sugar yields and low enzyme dosage.

β-Xylosidases of several fungi

, 1988
Publisher Summary This chapter describes the β-xylosidase from different fungi, such as Malbranchea pulchella var. sulfurea, Trichoderma viride, and Emericella nidulans, to compare their properties and modes of action on various substrates. β-Xylosidase of Malbranchea pulchella var. sulfurea activity is assayed spectrophotometrically by measuring the

Mechanism of Xylobiose Hydrolysis by GH43 β-Xylosidase

The Journal of Physical Chemistry B, 2010
Glycoside hydrolases cleave the glycosidic linkage between two carbohydrate moieties. They are among the most efficient enzymes currently known. β-Xylosidases from glycoside hydrolase family 43 hydrolyze the nonreducing ends of xylooligomers using an inverting mechanism.

Verrucomicrobia of the Family Chthoniobacteraceae Participate in Xylan Degradation in Boreal Peat Soils [PDF]

Microorganisms
The phylum Verrucomicrobiota is one of the main groups of soil prokaryotes, which remains poorly represented by cultivated organisms. The major recognized role of Verrucomicrobiota in soils is the degradation of plant-derived organic matter.

Ultrahigh-Throughput Screening of High-β-Xylosidase-Producing Penicillium piceum and Investigation of the Novel β-Xylosidase Characteristics. [PDF]

J Fungi (Basel), 2022
A droplet-based microfluidic ultrahigh-throughput screening technology has been developed for the selection of high-β-xylosidase-producing Penicillium piceum W6 from the atmospheric and room-temperature plasma-mutated library of P. piceum. β-xylosidase hyperproducers filamentous fungi, P. piceum W6, exhibited an increase in β-xylosidase activity by 7.1-

Comparison of glycoside hydrolase family 3 β-xylosidases from basidiomycetes and ascomycetes reveals evolutionarily distinct xylan degradation systems [PDF]

, 2022
Xylan is the most common hemicellulose in plant cell walls, though the structure of xylan polymers differs between plant species. Here, to gain a better understanding of fungal xylan degradation systems, which can enhance enzymatic saccharification of ...

Functional screening of a Caatinga goat (Capra hircus) rumen metagenomic library reveals a novel GH3 β-xylosidase.

PLoS ONE, 2021
Functional screening of metagenomic libraries is an effective approach for identification of novel enzymes. A Caatinga biome goat rumen metagenomic library was screened using esculin as a substrate, and a gene from an unknown bacterium encoding a novel ...
