Abstract: The general properties of cellulase in Neurospora crassa was studied in this paper. The results were as follows: the optimal conditions of enzymatic hydrolysis were at pH4.8~5.3, 45~50℃. Cellulase was stable at pH4.8 and 50℃, and the activity of CMCase, Clase and β-glucosidase were different from one another. The cellulase was activated by Mn2+, but inhibited by Cu2+ and Al3+. Adding washing powder into producting enzyme substrate could improve the activity of cellulase, but detergent liquid could inhibit the activity.

Key words: Neurospora crassa, cellulase, properties of enzyme
