Journal ArticleDOI
Production of fungal xylanases
TL;DR: Xylanase activities produced by different organisms, including filamentous fungi and yeasts, are compared for both submerged and solid-state fermentations, and data on the concurrent formation of cellulolytic enzyme activities are included.
Journal ArticleDOI
Increased production of laccase by the wood-degrading basidiomycete Trametes pubescens
TL;DR: By applying a fed-batch strategy, in which a glucose solution was fed continuously to a cultivation of T. pubescens so that the glucose concentration in the medium never exceeded a certain low, critical value, glucose repression could be avoided and production of laccase was almost doubled as compared to the batch cultivation.
Journal ArticleDOI
Extracellular electron transfer systems fuel cellulose oxidative degradation.

TL;DR: Different extracellular electron sources for LPMOs are characterized and compared: cellobiose dehydrogenase, phenols procured from plant biomass or produced by fungi, and glucose-methanol-choline oxidoreductases that regenerate LPMO-reducing diphenols, demonstrating that all three are functional and that their relative importance during cellulose degradation depends on fungal lifestyle.
Journal ArticleDOI
Characterization of the major laccase isoenzyme from Trametes pubescens and regulation of its synthesis by metal ions.
TL;DR: The major laccase isoenzyme LAP2 secreted by the white-rot basidiomycete Trametes pubescens in response to high copper concentrations was purified to apparent electrophoretic homogeneity using anion-exchange chromatography and gel filtration.
Journal ArticleDOI
Enhanced formation of laccase activity by the white-rot fungus Trametes pubescens in the presence of copper.
TL;DR: The stimulatory effect of Cu on laccase synthesis was also effective for several other basidiomycetes and hence could be used as a simple method to boost the production of this enzyme.
