【摘要】 根据微藻细胞营养元素含量对BG11培养基重新设计,改良培养基中主要营养盐浓度为（mg/L）:KH₂PO₄ 32,MgSO₄·7H₂O 32,（NH₄）₂SO₄ 22.4,CaCl₂·7H₂O 8,FeSO₄ 2.6.培养实验结果显示,改良培养基和BG11培养基中二形栅藻的初始生长状态几乎相同,最终油脂产量分别为0.407和0.403 g/L,改良培养基的培养成本为BG11培养基的33%⁵0%.更多还原

【Abstract】 An elemental balance approach between culture medium and biomass composition is used to redesign BG11 culture medium,the main nutrients in the modified culture medium are KH₂PO₄ 32 mg/L,MgSO₄·7H₂O 32 mg/L,（NH₄）₂SO₄ 22.4 mg/L,CaCl₂·7H₂O 8 mg/L,and FeSO₄ 2.6 mg/L.The results show that Scenedesmus dimorphus almost has the same initial growth curve in the modified and BG11 culture media,and the final volumetric yield of lipid is 0.407 and 0.403 g/L,respectively,in the case of reducing the cultivation cost to 33%⁵0%,Scenedesmus dimorphus in the modified and BG11 culture media almost obtains the same lipid yield.更多还原
