PHYSIOLOGICAL AND BIOCHEMICAL BASIS OF DEGRADATION OF LIGNOCELLULOSE BY HYPSIZYGUS MARMOREUS
玉蕈降解木质纤维素的生理生化基础

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.
