毛霉菌油对被孢霉产花生四烯酸的影响.pdf

6 3 生命科学研究 Vol. 6 No. 3 2002 9 Life Science Research Sep. 2002 周蓬蓬, 秦文敏, 余龙江, 朱 敏 ( , 430074) : 研究了不同浓度毛霉菌油对被孢霉产花生四烯 ( AA) 的影响, 发现0. 3% 毛霉菌油可以显著提高花生 四烯 产量, 并研究了0 . 3% 毛霉菌油在整 个发酵过程中对被孢霉产花生四烯 的影响. 结果表明, 毛霉菌油对 被孢霉生长和油脂产量基本上没有影响, 毛霉菌油可以提高被孢霉的AA 产量, 主要是因为其能提高AA 在油 脂中的含量. : 毛霉菌油 被孢霉 花生四烯 : Q81 : A :( 2002) Effect of Oil from Mucor on Mortierella Producing Arachidonic Acid ZHOU Pengpeng, QIN Wenmin, YU Longjiang, ZHU Min ( School of Lfi e Science Technology , Huazhong University of Science Technology , Wuhan 430074, H ubei , China) Abstract: Effects of various concentrat ion of oil from Mucor on Mortierella alp ina producing arachidonic acid ( AA) w ere studied. 0. 3% oil from Mucor resulted in the greatest AA production.Therefore, 0. 3% oil from Mucor was se lected to further study the effect of oil from Mucor on AA biosynthesis during the whole process .The results showed that : supplementation of oil from Mucor had no significant effect on Mortierella growth and total lipid yield. Oil from Mucor increasing AA yield w as mainly due to its stimulatory effect on AA content in total lipids.
