摘要
本文研究了玉蕈在纤维废弃物上生长期间,培养基中主要成分的降解规律及有关的酶学分析。实验结果表明:1.玉蕈分解纤维素和半纤维素的能力较强,分解木素的能力很弱。因此,玉蕈是褐腐型木腐菌。2.纤维素是玉蕈子实体生长阶段的主要碳源。3.玉蕈生长期间可向培养基中释放羧甲基纤维素酶、滤纸纤维素酶、半纤维素酶、淀粉酶和蛋白酶。酶活性在子实体生长阶段显著增加。进一步证明了子实体阶段酶活性增加与培养温度和子实体形成有密切关系。
The degradation of the main compounds in ligocellulosic waste materials and relative enzyme activities were investigated.The results showed that:1.Hypsizygus marmo- reus decomposed cellulose and hemicellulose strongly and lignin weakly.So it belongs to brown-rotting fungus.2.Cellulose is the main carbon source for the fruiting stage of H.mar- moreus.3.H.marmoreus released CMC-ase (carboxymenthel cellulose),FP-ase (fillter paper paper cellulase),hemicellulase,amylase and proteinase into substrates.Enzyme activity peaks were correlated to the appearence of the fructification.It further indicated that the increase of the enzyme activities were closely related to the cultivation temperature and fructification.
