【摘要】 通過正交試驗獲得一種蜜環菌母種培養基新配方(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%),在菌絲體產量和性狀方面優于目前常用的固體PDA加富培養基。利用板栗細小枝條和玉米芯的提取液添加至普通PDA培養基中,獲得改良的蜜環菌液體原種培養配方(馬鈴薯8%、蔗糖0.8%、板栗細小枝段3%、玉米芯碎塊3%)。與液體PDA加富培養基相比,菌球數目更多、個體更大、健壯度更高,且菌絲體產量最高可達2.5倍。板栗液玉米芯液組合使用后效果優于單獨添加,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...
