摘要

蛹蟲草（Cordyceps militaris）發酵能產生具有免疫調節、抗氧化、降血糖等生理活性成分。本研究採用小麥、薏仁和糙米三種穀類作為蛹蟲草固態發酵主要的基質；並分別加入豬腸膜蛋白粉、血漿蛋白粉、魚粉和酵母粉作為氮源，以探討培養基成分對蛹蟲草固態發酵生產蟲草素（Cordycepin）之影響。結果顯示，以小麥作為蛹蟲草固態發酵之基質，魚粉作為氮源進行發酵，於22°C環境下培養，在第35天可獲得最高量的蟲草素為11.31 mg/g。

Cordyceps militaris fermentation can produce imrnunomodulatory, antioxidant, hypoglycemic and other physical activity components. In this study, adlay, rice and wheat were three different media for Cordyceps solid-state fermentation. Moreover, dried porcine soluble, spray-dried plasma protein, fish meal, and yeast powder were used as different nitrogen sources in media in order to investigate the effects of medium on production of cordycepin by Cordyceps militaris solid-state fermentation. The results showed that using wheat as a major medium and fish meal as a nitrogen source for Cordyceps militaris solid-state fermentation at 22 °C could produce the highest concentration of cordycepin, 11.3 mg/g, after 35-days fermentation.
