【摘要】 报道了花生四烯酸生产菌被孢霉菌菌丝体老化对产花生四烯酸的影响。研究结果表明：不同培养时间的菌丝（３ｄ—７ｄ）在室温下老化１５ｄ，菌丝体中总脂含量由１８％—３０％上升至３６％—４１％；菌丝体中ＡＡ含量由１．１％—２．６％上升至２．６％—３．７％。但菌丝体油脂中ＡＡ含量在老化过程中没有显著变化。不同老化温度（５℃—２５℃）对菌丝体中ＡＡ含量没有显著影响。更多还原

【Abstract】 The effects of Mortierella M10 mycelial aging on production of arachidonic acid were investigated in this paper.Arachidonic acid content of Mortierella M10 increased from 18%-30% to 36%-41% during aging while lipid content of mycelium increased from 1 1%—2 6% to 2 6%—3 7%,but the proportion of arachidonic acid in lipids of mycelium remains constant during aging Temperature(5℃-25℃)of aging had little effect on arachidonic acid content更多还原
