【摘要】 研究了5種金屬離子Fe2+、Zn2+、Ca2+、Cu2+、Mg2+對(duì)蒙古口蘑的菌體生長(zhǎng)及胞外多糖的影響。結(jié)果表明,在培養(yǎng)基中添加5種金屬離子Fe2+、Zn2+、Ca2+、Mg2+和Cu2+,對(duì)菌體的生長(zhǎng)都有一定的抑制作用,但卻都能提高胞外多糖的產(chǎn)量,促進(jìn)作用依次為Zn2+>Fe2+>Ca2+>Cu2+>Mg2+,最大比對(duì)照分別提高了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+.
