摘　　要：用丝状真菌深黄被孢霉突变株发酵生产多不饱和脂肪酸,对高产多不饱和脂肪酸进行了优化培养研究,发酵生物量为51.308g/L,含油率为39.547%,产油量为20.291g/L,其油脂脂肪酸组成中不饱和脂肪酸含量为85.71%,其中γ-亚麻酸为6.68%。Mortierella isabellina mutant strain was utilized to produce polyunsaturated fatty acid by fermentation. The culture optimization was conducted for high PUFA yield. The amount of fermentative fungi was 51. 308 g （dry basis）per litre of fermented liquid. The dry fungi contained 39. 547% oil. The oil yield was 20. 291 g per litre of fermented liquid. Unsaturated fatty acids of the fungi oil was 85, 71% and the content of γ - linolenic acid was 6.68% .
