摘要:
二十碳五烯酸(eicosapentaenoic acid，EPA)对缓解心律不齐、高血压等疾病具有重要作用，对调节情绪、治疗风湿性关节炎及哮喘也具有积极意义。通过优化氮源和碳源、添加生长因子等途径提高菱形藻HE06的EPA产率。经优化得到硝酸钠、氯化铵、尿素、维生素B1、维生素B12、生物素、葡萄糖、甘油、碳酸氢钠的最佳质量浓度分别为 75 mg/L、5 mg/L、30 mg/L、1.5 mg/L、6 μg/L、10 μg/L、1.2 g/L、2.4 g/L、1.2 g/L。在最佳优化条件下，EPA产率由最初的31.2 μg/L提升至504.8 μg/L，提高了15倍；生物量产率由19.5 mg/L提高至32.4 mg/L，提高了66.2%。
