Hemicellulases in the bleaching and characterisation of kraft pulps: Dissertation

, 1996
Enzyme-aided bleaching of kraft pulps is the major industrial application of hemicellulases in pulp processing. In this work, the role of xylanase and mannanase pretreatments in the ECF and TCF bleaching of softwood pulps produced by different sulphate cooking methods was studied.

Structure-guided engineering of transcriptional activator XYR1 for inducer-free production of lignocellulolytic enzymes in Trichoderma reesei

Synthetic and Systems Biotechnology, 2023
The filamentous fungus Trichoderma reesei is widely used for the production of lignocellulolytic enzymes in industry. XYR1 is the major transcriptional activator of cellulases and hemicellulases in T. reesei.

A Fungal Secretome Adapted for Stress Enabled a Radical Wood Decay Mechanism

mBio, 2021
Brown rot fungi release massive amounts of carbon from forest deadwood, particularly at high latitudes. These fungi degrade wood by generating small reactive oxygen species (ROS) to loosen lignocellulose, to then selectively remove carbohydrates. The ROS

Modification of transcriptional factor ACE3 enhances protein production in Trichoderma reesei in the absence of cellulase gene inducer

Biotechnology for Biofuels, 2020
Background Trichoderma reesei is one of the best-known cellulolytic organisms, producing large quantities of a complete set of extracellular cellulases and hemicellulases for the degradation of lignocellulosic substances. Hence, T.

CAZymes from the thermophilic fungus Thermoascus aurantiacus are induced by C5 and C6 sugars

Biotechnology for Biofuels, 2021
Background Filamentous fungi are excellent lignocellulose degraders, which they achieve through producing carbohydrate active enzymes (CAZymes). CAZyme production is highly orchestrated and gene expression analysis has greatly expanded understanding of ...

Fusarium graminearum as a producer of xylanases with low cellulases when grown on wheat bran

Biotechnology Reports, 2022
The xylanolytic potential of endophytic fungi isolated from leaves of Theobroma cacao was explored for the first time. Four fungal strains showed significant amounts of xylanase activity and low cellulase levels when grown on wheat bran as the sole ...

Extracellular enzymes of Fusarium graminearum isolates

Brazilian Archives of Biology and Technology, 2010
Fusarium graminearum isolates from three different agroecological regions in Argentina were examined according to the production of different extracellular enzyme activities of potential biotechnological interest: pectinases (PGase: polygalacturonase and
