| 中文摘要: |
| 蛹虫草能产生虫草素等多种活性物质。为考察不同液体发酵方式及添加前体物质对虫草素积累的影响，选用蛹虫草08Y1菌株，通过光照振荡、光照静置、黑暗振荡、黑暗静置四种培养条件和添加前体物质（腺嘌呤1g/L+甘氨酸16g/L），发酵16d后检测虫草素和腺嘌呤含量。结果表明：08Y1菌株在黑暗振荡培养条件下，虫草素积累达1,015.0mg/L，腺嘌呤利用率达98.5%，说明黑暗振荡培养并添加前体物质是提高虫草素产量的有效方法。 |
| 英文摘要: |
| The medicinal fungus Cordyceps militaris produces many active metabolites including cordycepin (3￠-deoxyadenosine). The effects of additives and different liquid culture conditions on cordycepin production by C. militaris were investigated. The strain of C. militaris 08Y1 was used for optimizing liquid culture conditions (light and shaking, light and static, dark and shaking, dark and static), and the additives (adenine 1g/L+glycine 16g/L) were added to medium for 16 days. The maximum cordycepin production of 1,015.0mg/L was achieved by culture at dark and shaking with the supplement of additives, and the maximum utilization ratio of adenine reached 98.5%. The results showed that the condition of dark and shaking with the supplement of additives was an effective way for increasing the production of cordycepin. |
