| 摘 要： | 研究了灵芝菌经过低档绿茶萘汁、茶粉多次驯化后，平板培养时菌丝增殖速率和摇瓶发酵时菌体生物量与胞外粗多糖（EPS）的变化情况。实验结果表明，驯化种在茶汁平板和普通平板上，菌丝平均增殖速率分别提高了30．7％、8．0％；驯化种在茶培养基中发酵时，最大菌体生物量和胞外粗多糖产量分别提高了119．87％、69．39％。显然，驯化种发生了部分遗传特性良性改变。

| Abstract: | Gonoderma lucidum was repeatedly domesticated by tea liquor and tea powder. Then,the growth rate of mycelia in culture plates and the yield of cell biomass and EPS in shake flask fermentation were researched. The results indicated that the mycelia growth rate of domesticated strains in common and tea culture plates were raised by 8.0 %, 30.7 % respectively. Furthermore, the yield of cell biomass and EPS of domesticated strain in shake flask fermentation were increased by 119.87 %, 69.39 % respectively.Obviously,the tea domestication resulted to the positive genetic variation of Ganoderma lucidum. |
