| 中文摘要 | Nd3+, La3+ and Ce3+ at proper concentrations had positive effects on the cell growth of Arnebia euchroma and production of shikonin derivatives. A mixture of rare earth elements (MRE, La2O3:CeO2:Pr6O11: Sm2O3 = 255:175:3:1, mol/mol) behaved the most remarkable effects. Two-stage culture was used for the cell proliferation and the biosynthesis of shikonin derivatives. After 20 days culture, 0.05 mM MRE gave the highest cell biomass (24.8 g dry weight l(-1)), which was 98.0% higher than that without rare earth elements. Similarly, when 0.05 mM MRE was added to the biosynthesis medium, the highest content (8.9% dry weight) and production (571.1 mg l(-1)) of shikonin derivatives were obtained, which were 89.4% and 165.3% higher than those without rare earth elements, respectively. The increase of the cell biomass and shikonin derivatives may due to increasing the activities of peroxidase and phenylalanine ammonia lyase caused by the addition of the rare earth elements. |
