研究了48种Mucorales真菌在葵花籽油（含70%亚油酸；LA）上生长的脂质形成和γ -亚麻酸（GLA）的产生。菌株生物量脂质积累量为42.7 ~ 65.8% （7.66 ~ 13.39 g l(-1)）。8个培养物产生超过200 mg GLA l（-1）。GLA产量最高的是Mucor mucedo CCF-1384和Cunninghamella echinulata CCF-103（分别为379和373 mg l(-1)）。高山孢杆菌CCF-185合成了465 mg l（-1）花生四烯酸。脂质利用指数（细胞脂质中脂质含量与油源中脂质含量之比）的降低伴随着脂质化生物量的增长和细胞内脂质积累的减少，而高脂质产量是由于油源直接掺入细胞内脂质的结果。
Lipid formation and gamma-linolenic acid (GLA) production by 48 species of Mucorales fungi grown on sunflower oil (which consists of 70% linoleic acid; LA) were studied. The strains accumulated 42.7-65.8% lipid in biomass (7.66-13.39 g l(-1)). Eight cultures produced more than 200 mg GLA l(-1). Highest GLA yields exhibited Mucor mucedo CCF-1384 and Cunninghamella echinulata CCF-103 (379 and 373 mg l(-1), respectively). Mortierella alpina CCF-185 synthesized 465 mg l(-1) arachidonic acid. While the decrease of LA utilization index (ratio of LA content of cell lipid/LA content of oil source) was accompanied with growth of delipidized biomass and with reduction of lipid accumulation within the cells, high lipid yield was as a consequence of the direct oil source incorporation into intracellular lipid.
