【摘要】 通過(guò)正交試驗(yàn)獲得一種蜜環(huán)菌母種培養(yǎng)基新配方(葡萄糖2.5%、酵母粉0.2%、乙醇0.5%、K2PO40.03%、MgSO40.015%、VB10.001%、瓊脂粉1.5%),在菌絲體產(chǎn)量和性狀方面優(yōu)于目前常用的固體PDA加富培養(yǎng)基。利用板栗細(xì)小枝條和玉米芯的提取液添加至普通PDA培養(yǎng)基中,獲得改良的蜜環(huán)菌液體原種培養(yǎng)配方(馬鈴薯8%、蔗糖0.8%、板栗細(xì)小枝段3%、玉米芯碎塊3%)。與液體PDA加富培養(yǎng)基相比,菌球數(shù)目更多、個(gè)體更大、健壯度更高,且菌絲體產(chǎn)量最高可達(dá)2.5倍。板栗液玉米芯液組合使用后效果優(yōu)于單獨(dú)添加,以比例1:1效果最佳。
【Abstract】 A new medium(glucose 25%,yeast extract 2%,ethanol 0.5%,K2PO4 0.03%,MgSO4 0.015%,VB1 0.001% and agar powder 1.5%) for stock spawn of Armillaria mellea was obtained by orthogonal test.By using this medium,the growth of mycelia was superior to that of the widely used PDA solid medium both in biomass and traits.Another submerged culture medium(potato 8%,sucrose 0.8%,Castarea mollissima twigs 3%,chipped Corncob 3%) was also invented by adding Castarea mollissima twigs and corncob extracts into PDA me...
