Biocatalytic conversion of kraft pulp using cellulase complex of Penicillium verruculosum

Resumo

The efficiency of biocatalysts based on the cellulase complex from the Penicillium verruculosum fungus in the hydrolysis of kraft pulp from soft and hardwood is investigated. The activities of biocatalysts with respect to unbleached and bleached cellulose samples and the dependence of the degree of cellulose conversion on the content of noncellulose components are determined. It is shown that wet kraft pulp exhibits high reactivity in enzymatic hydrolysis with cellulase complex from P. verruculosum and is undoubtedly of interest as a substrate for scaling up biotechnological processes of the bioconversion of renewable plant-derived materials.
