Title:
ANAEROBIC DECOMPOSITION METHOD OF LIGNIN
Document Type and Number:
Japanese Patent JP2005185907
Kind Code:
A
Abstract:

To provide the method of practical treatment of lignocellulosic material by lignin decomposition bacteria in advance in an anaerobic condition for saving resources and energy in production of paper pulp, and a practical method for anaerobically decomposing lignin contained in draining liquid caused in the paper pulp production process.

In the anaerobic decomposition method of lignin, the lignin is decomposed by isolated lignin decomposition bacteria in the anaerobic condition. In this method, the isolated lignin decomposition bacteria are yeast belonging to genus Candida, in particular, to Candida tropicalis. Lignin present in the pulp drain as a coloring substance can be discolored by anaerobic decomposition using the bacteria.
