Abstract :
To screen stimulators for mycelial growth and polysaccharides production of Ganoderma lucidum, the fungus was inoculated into the media with and without supplementation of several fatty acids and ether extracts of Chinese medicinal insects. Palmitic acid at 1.0 g/L lead to significant increase in both biomass and extracellular polysaccharides (EPS) concentration from 7.73 plusmn 0.41 to 10.21 plusmn 0.43 g/L and 342.6 plusmn 10.7 to 401.3 plusmn 14.9 mg/L, respectively. In addition, ether extract of Eupolyphaga sinensis at 1.5 g/L also was of great advantage to biomass and EPS production. There were no new components in the EPS obtained by the addition of palmitic acid.
