摘要:
利用Sigmoid模型对比研究了添加9,10‐环甲基十七烷酸(9,10‐CMA)前后灵芝深层发酵产三萜酸的动态变化特征。研究显示,灵芝对照组中三萜酸在4–9d大量合成,并于第9天达到最大值(268.62mg/L);添加9,10‐CMA组中三萜酸的合成量于第8天时达到最大值(343.52mg/L)。添加9,10‐CMA后,灵芝菌丝体细胞对底物葡萄糖的利用速度加快,细胞比生长速率在3.2天达到最大值(M_(max)),为0.94d~(-1),显著高于对照组的0.88d~(-1)(在第3.4天获得);葡萄糖比消耗速率在第1.7天达到最大值(Q_(S, max)),为8.34d~(-1),显著高于对照组的6.80d~(-1)(在第2.1天获得)。胞内三萜酸比合成速率显著提高,在第6.2天达到最大值(QITA,...
摘要(英文):
The dynamic characteristics of triterpene acid produced by submerged fermentation of Ganoderma lingzhi before and after adding 9,10-methylene hexadecanoic acid (9,10-CMA) were studied by using Sigmoid model. The results showed that triterpene acids were mainly synthesized at days 4–9 and reached the maximum at day 9 (268.62mg/L) in experimental control, while the synthesis rate was relatively fast, reached the maximum at day 8 (343.52mg/L) under the treatment of adding 9,10-CMA. After adding 9,10-CMA, the utilization rate of substrate glucose ...
