摘  要:
研究了5种金属离子Fe2+、Zn2+、Ca2+、Cu2+、Mg2+对蒙古口蘑的菌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+,对菌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%。

摘  要:
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+.
