| Abstract: | Changes in several extracellular enzyme activity of Grifola frondosa cultivated on cottonseed hull compost were studied. The activity peaks of CMCase (carboxymethyl cellulase), FPCase (filter paper cellulase) and HCase (hemicellulase) coincided with the stage of fruiting body maturation. Amylase activity was at high level at the early stage of mycelial growth and decreased gradually after primordium formation. Peroxidase activity was at high level at the stage of mycelial growth. However, the activity greatly decreased during fruiting body development and no activity was observed after fruiting body maturation. |
