[Effect of different light of LED light quality on growth and antioxidant enzyme activities of Ganoderma lucidum].

OBJECTIVE

To study the effect of light quality on growth, antioxidant enzyme activities of Ganoderma lucidum mycelium.

METHOD

G. lucidum mycelium was cultured under different light qualities by light emitting diodes (LED). The growth G. lucidum mycelium was observed and antioxidant enzyme activities was determined in different growth periods.

RESULT

Under the red LED, the blue LED and dark condition (CK), the mycelium grew faster than that under other light qualities. The white LED resulted in a largest increase in the amount of the mycelium and always kept the activities of CAT high level. Major fluctuations of POD activities emerged under the green LED, while enhanced severely in the late phase. Under the yellow LED, the activities of SOD appeared high level. However, SOD activities on dark (CK) raised obviously in late period. At the late stage, the content of mycelium polysaccharides was significant higher than that under the blue LED.

CONCLUSION

The light quality could influence the growth and metabolism of G. lucidum mycelium.
