【摘要】 报导了花生四烯酸生产菌被孢霉菌（Ｍｏｒｔｉｅｒｅｌａｓｐ．Ｍ１０）菌丝体在贮存过程中油脂的变化。研究结果表明，不同培养时间的菌丝体（３～７ｄ）在室温下贮存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含量在贮存过程中根据不同培养时间显示出不同变化规律。不同贮存温度（５～２５℃）对菌丝体中ＡＡ含量没有显著影响。在ｐＨ为８．０时贮存更有利于菌丝体中花生四烯酸含量的提高。更多还原

【Abstract】 The effects of Mortierella sp.M10 mycelium storage on the production of arachidonic acid are investigated in this paper.Arachidonic acid content of Mortierella M10 increase from 18%～30% to 36%～41% during storage while lipid content of mycelium increase from 1 1%～2 6% to 2 6%～3 7%,but the proportion of arachidonic acid in lipids of mycelium vary differently according the different harvest time during storage.Temperature(5～25℃) of storage had little effect on arachidonic acid content.更多还原
