| 摘 要： | 研究了5种金属离子Fe2＋、Zn2＋、ca2＋、Cu2＋、Mg2＋对蒙古口蘑的茵体生长及胞外多糖的影响。结果表明，在培养基中添加5种金属离子Fe2＋、zn2＋、ca2＋、Mg2＋和Cu2＋，对茵体的生长都有一定的抑制作用，但却都能提高胞外多糖的产量，促进作用依次为Zn2＋〉Fe2＋〉Ca2＋〉Cu2＋）Mg2＋，最大比对照分别提高了280．3％、160．5％、83．6％、52．6％和19．2％。

| Abstract: | The effects of metal ions on mycelium growth and extracellular polysaccharide production of Tricholoma mongolicum during fermentation were studied.The results indicated that all of five metal ions including Fe2+,Zn2+,Ca2+,Mg2+ and Cu2+ could inhibit mycelium growth.However,they could promote polysaccharide production,and 52.6%,83.6%,280.3%,160.5% and 19.2% were increased by respectively compared with the control with the order of Zn2+>Fe2+>Ca2+>Cu2+>Mg2+. |
