Popis: The aim of this work was to create biocatalysts with an increased heterologous expression of endo-β-1,4-xylanase of P. canescens using recombinant P. verruculosum strains, to analyze the properties of new enzyme preparations, and to study the saccharifying activity of these preparations in the hydrolysis of plant raw materials, such as hogged aspen and detarred pine wood wastes of the timber and wood processing industries. The xylanase activity of the existing enzymatic preparations is insufficiently high to hydrolyze a xylan-rich biomass. The creation of increasingly xylanolytically active P. verruculosum-based recombinant strains containing homologous or heterologous genes of xylanase and mannanase is therefore a problem of great interest.
