Application of Complex Biocatalysts Based on Recombinant Penicillium verruculosum Enzyme Preparations in the Hydrolysis of Semichemical Hardwood Pulp

摘要

A comparative study of the efficiency of the biocatalysts based on recombinant enzyme preparations obtained from the Penicillium verruculosum fungus in the hydrolysis of semichemical hardwood pulp is performed. The activity of the biocatalysts with respect to different types of semichemical pulp and the dependence of the depth of exhaustive hydrolysis on its beating and drying is determined. It is shown that semichemical pulp after cooking with green liquor displays high reactivity in enzymatic hydrolysis with cellulase complex and is of clear interest as a substrate for scaling the bioengineering processes of renewable plant feedstock conversion.
