【中文摘要】 試驗(yàn)研究了冬蟲(chóng)夏草(Cordyceps sinensis)蝙蝠蛾擬青霉(Paecilomyces hepiali Chen et Dai)菌絲體的發(fā)酵條件,其適宜接種量為2.5％～5.0％(v/v),最佳菌齡為3d,適宜的初始pH為5.0～7.5,發(fā)酵周期5d,發(fā)酵過(guò)程中對(duì)通氣量的要求較高。以20m3發(fā)酵罐培養(yǎng),菌絲體收率為2.5％,其D-甘露醇含量8.3％,腺苷含量0.24％。

【英文摘要】 The mycelial fermentation conditioas of Paecilomyces hepiali Chen et Dai of Cordyceps sinensis were studied in our last. The mycelia were cultured at 24℃ on a rotary shaker at 120 r/min for 5 days. It was proved that the suitable initial pH of the medium was 5.0 - 7.5, the inoculation ratio was 2.5% -5.0%(v/v) and the optimal spawn age was 3 days, and that more attention should be paid to the aeration during the fermentation process. Fermented in 20m3 fermentor, the yield of mycelia was 2. 5% .among which the content of D- mannitol in the dried mycelium was 8.3% and the content of adenosine was 0. 24% .
