Title: Kraft pulp bleaching and delignification by dikaryons and monokaryons of trametes versicolor

Abstract

To reduce the levels of chlorinated lignin residues in effluents from the pulp and paper industry, interest has focused on the white rot basidiomycete fungi. The kraft process, the most common commercial delignification method, produces a dark pulp which is bleached by use of chlorine, chlorine dioxide, and caustic extraction. A dikaryon of Trametes (Coriolus) versicolor has been shown to bleach and delignify kraft pulp, offering a possible alternative to chlorine. A monokaryon strain, if comparable to the effect of the dikaryon, would be a much simpler system for study of mechanisms and genetic munipulation. The researchers compared strains of both and conclude that the following characteristics justify replacing the parent dikaryon with monokaryon 52J in future work on biobleaching and biological delignification: (1) reduced biomass and slower growth rate; (2)no dark pigment production; (3) superior biological bleaching ability; (4) a simpler system for genetic manipulation and biochemical analysis. The involvement of MnP, but not LP, in pulp bleaching, delignification is strongly suggested. 40 refs., 3 figs., 4 tabs.
