Abstract:

In this study,carbon utilization of Ganoderma lucidum was analyzed following CO2 emission and lignocellulose degradation during colonization of substrate and during fruiting body formation. The results show that during growth of G. lucidum the utilization rate of carbon was 48.3% of which 12.5% of carbon was converted into the fruiting body and 35.8% of the carbon was emitted in the form of CO2. CO2 emission peaked at three times,respectively when the mycelium finished colonizing the substrate,during primordium formation,and during fruiting body maturation. Cellulose and hemicellulose were mainly degraded during colonization of the substrate by the mycelium up to primordium formation,while lignin was mainly degraded during the growing period of the fruiting body.

Key words: Ganoderma lucidum, carbon, CO2 emission flux, lignocellulose
