摘要
本文介绍了我们最近研究白腐菌(Panus conchatus)对稻草的生物降解规律方面的进展。利用扫描电子显微镜揭示了该菌对稻草的生物降解作用的整个微观过程,和稻草组织内部以及纤维细胞壁的微观结构的变化;探讨了几个重要生理条件对稻草降解过程所产生微观结构变化和木素降解作用的影响,同时,还着重对稻草生物降解过程中纤维素降解情况作出了估计。最后,根据研究结果,从制浆造纸角度讨论了发展稻草生物制浆的有利条件和潜在应用优势。
Recent advances in Modelignification of rice straw by a white-rot fungus, Panus Conchatus, have been attributed to three complementary approaches: (1) Elucidation of the growth pattern of the fungus in rice straw and the changes in straw ultrastructure through progressive biodegradation. (2) Influences of physiological parameters on microbial delignification and ultrastructural changes of straw. (3) Estimation of concomitant biodegradation of cellulose during progressive biodelignification. These approaches provides potential superiority for developing non-wood biopulping and other delignification processes using this particular fungus.
