木质素生物降解与生物制浆的研究现状分析

综述了木质素生物降解与生物制浆的研究现状 ,包括木质素降解代谢产物和降解途径与机制的研究、参与木质素降解的酶及其作用机制的研究、木腐菌对木材和木质素降解能力的研究以及高效降解木质素的生物制浆用优异菌株的筛选。对木质素生物降解与生物制浆的研究进行了展望。结果表明 :生物制浆由于既节省能源又有环境友好的特性而具有毋庸置疑的应用前景 ,在我国加强木质素生物降解和生物制浆的研究是势在必行的 ,这对于保护环境 ,缓解能源危机以及制浆造纸业的可持续发展都具有重要的意义。

Research Situations of Lignin Biodegradation and Biopulping

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.
