Comparison of the efficiency of plant materials bioconversion processes using biocatalysts based on enzyme preparations Trichoderma and Penicillium Verruculosum
Abstract
There is comparative study of the effectiveness of six commercial biocatalysts based on enzyme preparations derived from fungus of the genus Trichoderma as a producer (Cellic CTec1, Cellic CTec2, Accelerase 1000, Accelerase 1500, Accelerase XY, Accelerase DUET), and laboratory biocatalysts based on enzyme preparations derived from the fungus Penicillium verruculosum, for the hydrolysis of four types of plant cellulose material (steam pretreated corn stalks and bagasse, crushed timber pine and aspen), also microcrystalline cellulose. The activity of biocatalysts relative to various substrates and the dependence of the depth of exhaustive hydrolysis of plant material from the dosage of these biocatalysts were determined. It is shown that biocatalysts derived from P. verruculosum strains are competitive with the widely used commercial biocatalyst based on Trichoderma strains when they scale biotechnological processes bioconversion of renewable resources.
