Abstract:

Research situations of lignin biodegradation and biobulping were summarized, including study on catabolites and approach and mechanism of lignin biodegradation,ligninolytic enzymes and their function, the degrading abilities to wood and lignin of wood rotting fungi,and screening effective and selective isolates for biopulping. A prospect for lignin biodegradation and biobulping was looked ahead also. Results showed it was no doubt that biopulping would have a bright and promising future in pulp and paper industry because of its both economizing energy and friendly to environment. Now it is necessary to enhance the research work of lignin biodegradation and biopulping in China, which is very significant meaning to the sustaining development of pulp and paper industry.

Key words: Lignin, Biodegradation, Biobulping
