[Comparison of Laccase Activity of Different Strains of Ganoderma spp.]
Objective:
To explore the relationship between the laccase activity and growth of Ganoderma spp.,to screen the highproducing laccase strains.
Methods:
The mycelium was cultured in PDA solid medium,and the laccase activity was measured by ABTS+method. The content of polysaccharide was determined by phenol sulfuric acid method.
Results:
Ganoderma gibbosum grew more rapidly in the early stage,and the laccase activity reached maximum( 1 476. 64 U/g) in the 4th day,which was 11. 37 times larger than that of sweet Ganoderma lucidum. Ganoderma gibbosum had the significant advantage after a comprehensive analysis. The polysaccharide content of Ganoderma lucidum of Shinshu was lower; the growth rate of Ganoderma lucidum strain S3 was stable, and the content of polysaccharide was medium.
Conclusion:
There are some differences in the growth rate of Ganoderma spp., and there is a certain correlation between the laccase activity and growth. Ganoderma gibbosum is the highest-producing laccase strain among the screening strains.
