Comparing the Efficiency of Plant Material Bioconversion Processes Using Biocatalysts Based on Trichoderma and Penicillium verruculosum Enzyme Preparations

A comparative study of the effectiveness of six commercial biocatalysts based on enzyme preparations derived from a fungus of the genus Trichoderma as a producer (Cellic Ctec-1, Cellic Ctec-2, Accelerase 1000, Accelerase 1500, Accelerase XY, Accelerase DUET), and of laboratory biocatalysts based on enzyme preparations derived from the fungus Penicillium verruculosum for the hydrolysis of the four types of plant cellulose material (steam explosion pretreated corn stalks and bagasse, ground pine and aspen), and of microcrystalline cellulose is performed. Biocatalysts activities toward various substrates, and the dependence of the depth of exhaustive hydrolysis of plant material on the dosage of these biocatalysts are determined. It is shown that biocatalysts based on the strains of P. verruculosum are competitive with widely used commercial biocatalysts based on the Trichoderma strain if we scale the biotechnological processes of bioconversion of renewable plant raw materials.
