Production of xylanase by a new strain of Thermoascus aurantiacus: obtainment of enzymatic extract with reduced cellulolytic activity for application in pulp and paper industries

Bioscience Journal, 2016
Xylanases are useful in several industrial segments, including pulp and paper bleaching, animal feed, and bread-making processes. However, the industrial use of these enzymes is closely related to its production cost and its catalytic properties.

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Thermomyces lanuginosus: properties of strains and their hemicellulases [PDF]

FEMS Microbiology Reviews, 2003
The non-cellulolytic Thermomyces lanuginosus is a widespread and frequently isolated thermophilic fungus. Several strains of this fungus have been reported to produce high levels of cellulase-free beta-xylanase both in shake-flask and bioreactor cultivations but intraspecies variability in terms of beta-xylanase production is apparent.

Treatment of recycled kraft pulps with Trichoderma reesei hemicellulases and cellulases

, 2000
Effects of recycling ECF-bleached softwood kraft pulp on pulp properties were evaluated in the laboratory. The tensile strength, fiber flexibility and WRV lost during drying of the pulp were recovered by refining between the cycles which, however ...

Safety evaluation of the food enzyme mannan endo‐1,4‐β‐mannosidase from the non‐genetically modified Aspergillus niger HBI‐GM01

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The food enzyme mannan endo‐1,4‐β‐mannosidase (1,4‐β‐d‐mannan mannanohydrolase; EC 3.2.1.78) is produced with the non‐genetically modified Aspergillus niger strain HBI‐GM01 by HBI Enzymes Inc. The food enzyme was considered free from viable cells of the production organism.

An Engineered Laccase from Fomitiporia mediterranea Accelerates Lignocellulose Degradation

Biomolecules
Laccases from white-rot fungi catalyze lignin depolymerization, a critical first step to upgrading lignin to valuable biodiesel fuels and chemicals. In this study, a wildtype laccase from the basidiomycete Fomitiporia mediterranea (Fom_lac) and a variant

Metabolic engineering strategies for the improvement of cellulase production by Hypocrea jecorina

Biotechnology for Biofuels, 2009
Hypocrea jecorina (= Trichoderma reesei) is the main industrial source of cellulases and hemicellulases used to depolymerise plant biomass to simple sugars that are converted to chemical intermediates and biofuels, such as ethanol.
