LIGNIN DECOMPOSITION USING LACCASE AND LIGNIN DECOMPOSING AGENT

摘要

PROBLEM TO BE SOLVED: To efficiently decompose lignin in pulp without using a chlorine-based chemical by using both a laccase-containing substance and a composition containing terremutin and/or terreic acid. ;SOLUTION: Lignin of scrap wood, pulp, etc., is decomposed by using a lignin decomposing agent obtained by mixing a laccase-containing substance composed of a cultured product of at least one laccase producing fungus selected from the group consisting of Schizophyllum commune, Coriolus versicolor, Pycnoporus coccineus, Pleurotus octreatus and Fomitella fraxinea or its treated substance with a composition containing terremutin of formula I and/or terreic acid of formula II composed of a cultured product of a fungus Aspergillus capable of producing terremutin and terreic acid or its treated substance.;COPYRIGHT: (C)2000,JPO
