Method for increasing the efficiency of the chemical pulp process by pre-treatment by white rot fungi

摘要

(57) Basi Jioma Ise test given (Basidiomycetes) fungi, white rot fungi, for example Furebia-Toremerosa, birds chapters Tum-Biforume, of Faneroshete-Jigantea and Shizofirumu-Konmi ~Yu down, [summary] The present invention, quality products, especially on the use of in helping to pre-conditioning the pulp wood or wood to produce the process more efficient and uniform than bring. Increasing the porous timber support comprising a non-sterile timber support particular also found that such treatments. Liquid penetration increased into the cells of the wood pulp or wood more porous in the chemical processing step subsequent accompanied by such a rise in porous. Despite the fact the fact that leaving a cavity in a location that has been the removal of resin and pitch and / or obtained, white rot fungi of selection to penetrate deeply, or cell wall that is modified, take cavity of pulp wood in the pulp or that there is that it will not have any substantial effect on the lignin content has been found. Nevertheless, after it has been subjected to chemical treatment then, fungus treated pulp obtained shows a significant reduction in viscosity without an increase in brightness, a simultaneous reduction in kappa value and increase the yield. A method for reducing electrical energy consumption during mechanical refining leading to pulp wood or wood invention further pitch reduction an effective amount selected from the group consisting of the fungi on at least one end of the timber or the timber The machine timber or timber grown for sufficient time to reduce the pitch of the timber or timber this in Oyobi on the timber or wood fungus, and inoculated with fungi of the kind, it is then processed in this way at least relates to a method comprising that you entrust to refining.
