| 摘 要： | 研究了3种无机盐对隐甲藻(Crypthecodinium cohnii ATCC30556)生长及DHA产量的影响.结果表明隐甲藻可在NaCl为唯一无机盐的培养基中生长;培养基中NaCl质量浓度为6 g/L,Mg2+浓度为13.23 mmol/L,PO43-浓度为7.19 mmol/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3.31 g/L和499.93 mg/L.

| Abstract: | The effect of various mineral salts on the growth and DHA accumulation was determined in Crypthecodinium cohnii ATCC30556. Crpythecodinium cohnii ATCC 30556 could grow on the medium in which NaCl was the sole mineral salt. The medium which included 6 g/L NaCl, 13.23 mmol/L Mg 2 and 7.19 mmol/L PO 4 3- met the metal salts requisite, the amount of biomass reached 3.13 g/L and the yield of DHA 499.93 mg/L. |
