研究了 3种无机盐对隐甲藻 (Crypthecodinium cohnii ATCC30 5 5 6 )生长及 DHA产量的影响。结果表明 :隐甲藻可在 Na Cl为唯一无机盐的培养基中生长 ;培养基中 Na Cl质量浓度为 6 g/ L ,Mg2 + 浓度为 13.2 3mmol/ L ,PO43 -浓度为 7.19mmol/ L可满足藻细胞生长和 DHA积累的需求 ,此时隐甲藻有着最大的生物量和 DHA产量 ,分别为 3.31g/ L和 4 99.93mg/ L。 The effects of three inorganic salts on the growth and DHA production of Crypthecodinium cohnii ATCC305 5 6 were studied. The results showed that Crypthecodinium could grow in medium with NaCl as the sole inorganic salt. The concentration of NaCl in the medium was 6 g / L, the concentration of Mg2 + was 13.2 3 mmol / L, the concentration of PO43 - was 7.19 mmol / L It can meet the needs of algae cell growth and DHA accumulation, when Crypthecodinium has the largest biomass and DHA yield, respectively 3.31g / L and 499.93mg / L.
