摘　　要：研究了不同白腐真菌侧耳Z17、921、1024菌株对稻草秸秆的降解过程中培养物的胞外蛋白含量、木质纤维素结构及其有关酶活变化的影响。结果表明,在整个培养期间培养物的胞外蛋白含量、木质纤维素的降解率逐渐升高;酶活性变化较明显;木质纤维素结构变化明显。The extracellular protein content of the culture, the change of the structure in lignocellulose during degradation lignocellu-lose and the relative enzyme activity were determined with rice straw treated by different strains of white rot fungi( Pleurolus sp. )Z17. 921 and 1024 strains. The results revealed that the extracellular protein contents of the culture and the degradation rale of the lignocellulose were increased gradually during cultivation time; the increase in the activities of peroxidase and guaiacolase was significant and the changes of structure were significant during the cultivation.
