Abstract:

Cell suspension culture of Saussurea medusa Maxim. was established in a 2 L stirred bioreactor for flavonoids production. After 12 days of culture, the biomass was 10.35 g DW·L-1, containing 428.6 mg/L flavonoids, which was 4.14% of the biomass (dry weight) under the condition of 25 ℃ and light intensity lower than 5 μmol·m-2·s-1. The utility pattern of sugar, change of dissolved oxygen and oxygen uptake rate were also studied.
