The production of intracellular and extracellular triterpene acids of Ganoderma lucidum were studied in liquid fermentation. The results showed that the optimum fermentation conditions were as follows： culture temperature is 30 ℃, shaking speed is 160 r/min, liquid volume in flask （250 mL） is 80～100 mL, inoculum concentration is 10% （v/v）, initial pH is 5.5～6.0, and culture time is 7d. Under theses conditions, the production yield of intracellular and extracellular triterpene a...
