| 中文摘要: |
| 以热带海洋富油微藻XG01（琴式菱形藻，Psammodictyon panduriforme）为研究对象，测定了培养基中不同质量浓度的氮盐、磷酸盐和硅酸盐对藻株XG01生长和油脂产量的影响，确定了最佳培养条件，氮盐（硝酸钠）、磷酸盐（磷酸二氢钠）和硅酸盐（九水偏硅酸钠）的最佳质量浓度分别为300、10 mg/L和20 mg/L。在最佳培养条件下，藻株XG01的生物量达0.85 g/L，藻细胞内的油脂含量和油脂产量分别为48.21%和0.41 g/L。 |
| 英文摘要: |
| The effects of different mass concentrations of nitrogen salt，phosphate and silicate on the growth and oil production of oil-rich tropical marine microalgae XG01 （Psammodictyon panduriforme） were measured. The optimal cultural conditions were obtained as follows：mass concentrations of nitrogen salt（NaNO3），phosphate （NaH2PO4） and silicate （Na2SiO3·9H2O） were 300，10 mg/L and 20 mg/L respectively. Under the optimal cultural conditions，the biomass，oil content and oil production in the cell of microalgae XG01 were up to 0.85 g/L，48.21% and 0.41 g/L respectively. |
