摘　　要：本文分析了银耳与其伴生菌在木屑培养基和废棉渣培养基上生长期间,栽培基质中主要成分的降解规律及其有关的酶学基础。试图从营养生理角度探讨银耳与其伴生菌之间的生态关系。实验结果表明,银耳菌单独在木质纤维素上生长时,不能形成子实体。当银耳与伴生菌生长在一起时,银耳菌在木质纤维废物上生长发育良好,可形成子实体。银耳子实体生长对培养基中的纤维素降解有促进作用。The nutritional ecophysiology of Tremella fuciformis and its associated fungus growing on cellulosewaste is studied. The results show: 1) Tremella fuciformis grows too poor to develop fruit bodies when cultivated alone on cellulose-waste, but grows very well and produces fruit bodies normally when cultivated together its associated fungus on the same medium; 2) cellulose is the main carbon resource for two fungi during fruitification; 3) there is an enzymatic coordinating effect between the two fungi in cellulose degradation; and 4) the fruitification of Tremella fuciformis can promote cellulose degradation.
