Production of xylanolytic enzymes by Aspergillus terricola in stirred tank and airlift tower loop bioreactors [PDF]

open access: yes, 2011
Fungi producing high xylanase levels have attracted considerable attention because of their potential industrial applications. Batch cultivations of Aspergillus terricola fungus were evaluated in stirred tank and airlift bioreactors, by using wheat ...

Conversion of xylan by recyclable spores of Bacillus subtilis displaying thermophilic enzymes [PDF]

open access: yes, 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.

Coordinately express hemicellulolytic enzymes in Kluyveromyces marxianus to improve the saccharification and ethanol production from corncobs

open access: yesBiotechnology for Biofuels, 2021
Background Hemicellulose acts as one factor contributing to the recalcitrance of lignocellulose that prevents cellulases to degrade the cellulose efficiently even in low quantities.

Glycosidases separation and their relation to alcohol aroma production in the flowers of Gardenia Jasminoides E

open access: yes浙江大学学报. 农业与生命科学版, 2000
Glycosidases were separated with CM-Toyopearl 650M column chromatography in this study. The collected liquid was divided into eleven fractions from A to K by the activities of three glycosidases β-Glucosidase, β-Xylosidase and β-Primeverosidase.

Molecular cloning, expression, and characterization of four novel thermo-alkaliphilic enzymes retrieved from a metagenomic library

open access: yesBiotechnology for Biofuels, 2017
Background Enzyme discovery is a promising approach to aid in the deconstruction of recalcitrant plant biomass in an industrial process. Novel enzymes can be readily discovered by applying metagenomics on whole microbiomes.

Transcriptomic analysis reveals the hepatic response mechanisms of the Chinese spiny frog (Quasipaa spinosa) to Citrobacter freundii infection

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract To elucidate the pathogen and host response mechanisms underlying mass mortality in Quasipaa spinosa, dominant bacteria were isolated from diseased individuals and identified as Citrobacter freundii by morphological, physiological, and biochemical characterization, 16S rRNA sequencing, and phylogenetic analysis.

Novel GH115 xylan α‐1,2‐glucuronidases with distinct preferences for xylan‐derived oligomers and polymers

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Natural polymers are promising sustainable materials for diverse applications. Xylans, major components of hemicellulose, exhibit origin‐dependent substitution patterns that determine their physicochemical properties. Targeted enzymatic modification of these substituents offers a mild and precise approach for tailoring the polymer's ...

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

open access: yesPeerJ, 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 ...

Necromass chemistry drives the functional diversity of the necrobiome, resulting in microbe–organic matter feedbacks

open access: yesFunctional Ecology, Volume 40, Issue 5, Page 1339-1351, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In temperate European forests, soil fungal communities, dominated by saprotrophic and ectomycorrhizal (ECM) species, represent almost 25% of soil organic carbon (C) in the soil.
