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。
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 （ NaH2 PO4 ） and silicate （ Na2 SiO3 ·9H2 O） 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.
