Characterization of the Highly Efficient Acid-Stable Xylanase and β-Xylosidase System from the Fungus Byssochlamys spectabilis ATHUM 8891 (Paecilomyces variotii ATHUM 8891)

Journal of Fungi, 2021
Two novel xylanolytic enzymes, a xylanase and a β-xylosidase, were simultaneously isolated and characterized from the extracellular medium of Byssochlamys spectabilis ATHUM 8891 (anamorph Paecilomyces variotii ATHUM 8891), grown on Brewer’s Spent Grain ...

Gene Disruption of an Arabinofuranosidase/β-Xylosidase Precursor Decreases Sclerotinia sclerotiorum Virulence on Canola Tissue

Molecular Plant-Microbe Interactions, 2009
Although Sclerotinia sclerotiorum (Lib.) de Bary has been studied extensively, there are still aspects of this important phytopathogen's ability to cause disease in susceptible plants that remain unclear.

Effects of Two-stage Controlled pH and Temperature vs. One-step Process for Hemicellulase Biosynthesis and Feruloyl Oligosaccharide Fermentation using Aureobasidium pullulans

BioResources, 2016
A two-stage, pH- and temperature-controlled wheat bran fermentation method using Aureobasidium pullulans was investigated for feruloyl oligosaccharides (FOs) production and the activities of xylanase, xylosidase, and ferulic acid esterase (FAE).

Carbon‐Fixing Bacterial Network Complexity Mediates Soil Multifunctionality in a Panax notoginseng‐Pinus armandii Agroforestry System

Land Degradation &Development, EarlyView.
ABSTRACT Autotrophic carbon‐fixing bacteria (CFB) are central contributors to soil carbon sequestration and biogeochemical carbon cycling in agroforestry ecosystems and can act as reliable biological indicators for evaluating agroforestry ecosystem sustainability.

Wheat domestication accelerated evolution and triggered positive selection in the beta-xylosidase enzyme of Mycosphaerella graminicola. [PDF]

PLoS ONE, 2009
Plant cell wall degrading enzymes (PCWDEs) of plant pathogens are receiving increasing interest for their potential to trigger plant defense reactions. In an antagonistic co-evolutionary arms race between host and pathogen, PCWDEs could be under strong ...

Deep Straw Incorporation With Supplemental Fertilization Improves Subsoil Quality and Maize Productivity

Land Degradation &Development, EarlyView.
ABSTRACT Deep straw incorporation is widely advocated for enhancing crop yields and improving agroecosystem functions and services. However, how this practice interacts with different fertilization strategies synergistically to influence soil quality and maize productivity remains unclear.

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Identification and Molecular Characterization of the First α-Xylosidase from an Archaeon [PDF]

Journal of Biological Chemistry, 2000
We here report the first molecular characterization of an alpha-xylosidase (XylS) from an Archaeon. Sulfolobus solfataricus is able to grow at temperatures higher than 80 degrees C on several carbohydrates at acidic pH. The isolated xylS gene encodes a monomeric enzyme homologous to alpha-glucosidases, alpha-xylosidases, glucoamylases and sucrase ...

HYPER-PRODUCTION OF ΒETA-GLUCOSIDASE AND ΒETA-XYLOSIDASE BY ASPERGILLUS NIGER NCIM 1207 IN XYLAN CONTAINING MEDIA [PDF]

BioResources, 2011
Aspergillus niger NCIM 1207 produced significantly high levels of β-glucosidase and β-xylosidase activities in submerged fermentation. Cellulose induced only β-glucosidase, while xylan induced both β-glucosidase and β-xylosidase activities.
