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.

Glucose Modulates Marine Xylanase Activity: Insights From Caulerpa lentillifera and Synthetic β-1,3-glucoxylans. [PDF]

Chembiochem
Two recombinant xylanases from marine bacteria, β‐1,3‐xylanase Xyl4 and mixed‐linkage xylanase AlXyn26A, were used to digest glucoxylan structures extracted from the green alga Caulerpa lentillifera and synthesized by automated glycan assembly. High‐performance liquid chromatography coupled with mass spectrometry (HPLC‐MS) analysis of the reaction ...

Xylella fastidiosa Requires Polygalacturonase for Colonization and Pathogenicity in Vitis vinifera Grapevines

Molecular Plant-Microbe Interactions, 2007
Xylella fastidiosa is the causal agent of Pierce's disease of grape, an economically significant disease for the grape industry. X. fastidiosa systemically colonizes the xylem elements of grapevines and is able to breach the pit pore membranes separating

A multifunctional GH39 glycoside hydrolase from the anaerobic gut fungus Orpinomyces sp. strain C1A [PDF]

PeerJ, 2016
Background. The anaerobic gut fungi (phylum Neocallimastigomycota) represent a promising source of novel lignocellulolytic enzymes. Here, we report on the cloning, expression, and characterization of a glycoside hydrolase family 39 (GH39) enzyme (Bgxg1 ...

Evaluation of new xylanolytic-producing isolates of Aspergillus from Misiones subtropical rainforest using sugarcane bagasse

Arab Journal of Basic and Applied Sciences, 2019
Xylanases hydrolyse efficiently the xylan component of hemicelluloses into single xylose monomers. Hence, these enzymes are suitable to be applied in the bioconversion of lignocellulosic wastes such as sugarcane bagasse to improve the bioethanol process.

Gene sets for utilization of primary and secondary nutrition supplies in the distal gut of endangered Iberian lynx. [PDF]

PLoS ONE, 2012
Recent studies have indicated the existence of an extensive trans-genomic trans-mural co-metabolism between gut microbes and animal hosts that is diet-, host phylogeny- and provenance-influenced.

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.

Structural and Functional Insights Into CmGH1, a Novel GH39 Family β-Glucosidase From Deep-Sea Bacterium

Frontiers in Microbiology, 2019
Glucosidases play key roles in many diseases and are limiting enzymes during cellulose degradation, which is an important part of global carbon cycle. Here, we identified a novel β-glucosidase, CmGH1, isolated from marine bacterium Croceicoccus marinus ...
