摘要:DHA(二十二碳六烯酸)在婴幼儿大脑发育和视力发育中具有非常重要的生理作用,并且具有防治心血管疾病,提高人体免疫力
和消炎、抗癌等功能。 DHA 的来源有多种,在寇氏隐甲藻(Crypthecodinium cohnii)的细胞油脂中,DHA 的含量高达 30%~50%,而其他多不
饱和脂肪酸(PUFAs)含量较少,寇氏隐甲藻可以在添加了有机底物的培养基中高密度发酵,是人体补充 DHA 的良好来源。

Abstract:DHA is a polyunsaturated fatty acid that belongs to the ω-3 recent years,DHA has attracted much attention
because it plays an important role in human cohnii is extraordinary in DHA and it can be grown
heterotrophically anic substrates without is a prolific producer of paper reviews recent advances in the
biotechnological production of DHA by C. cohnii.
