摘要
为了提高深黄被抱霉产生γ－亚麻酸的量，对原生质体进行了紫外线诱变，实验表明采用紫外线（UV）照射45s，可获得高产突变株，突变株MH23、MH18和MX26分别比对照株M6－22的γ－亚麻酸产量提高了70．7％、54．1％和53．6％．表明用原生质体进行诱变处理是较好的方法．
The feasibility of the protoplast-UV mutagenesis for increasing γ-lindenic acidwas studied on MOrtierella isabellina stain. The experimentS showed that the high mutantSwere obtained by UV-irradiation of the ProtoplastS with 45 seconds. The γ-lindenic acidcontent of the mutant Mad,MH,and MX,was respechvely increased 70.7%, 54.1% and53.6% than that of the contra St strain Me-22.The resultS indicated that the protoplastmutagenesis is a better a PProach tO increase γ-lindenic acid yield of Misabellina.
