摘要:该文通过对洛伐他汀生产菌红曲霉S-01固态发酵工艺条件的研究,确定了固态发酵的最佳工艺条件:发酵培养基配方为大米2500g、甘油75g、蛋白胨175g、初始含水量40%,按装载量350g/1.5L进行装瓶,接种量25%,于30℃发酵7d(前发酵),23℃发酵33d(后发酵),经过优化后的红曲固态发酵产洛伐他汀的含量达到14.38mg/g,酸式(开环)洛伐他汀含量为9.35mg/g,酸式(开环)洛伐他汀占比为65.02%。该研究对功能红曲的工业化生产有一定的指导意义。

Abstract:In this paper, the solid-state fermentation conditions of lovastatin producing strain Monascus S-01 were studied,and the best solid-state fermentation conditions were determined:rice 2 500 g,glycerium 75 g, peptone 175 g,initial moisture content 40%,bottling with 350 g/1.5 L,inoculum volume 25%,30 ℃ for 7 d(pre-fermentation),23 ℃ for 33 d (post-fermentation),optimized yield of lovastatin by Monascus in solid-state fermentation was 14.38 mg/g,acid (ring-opening) lovastatin was 9.35 mg/g,and the proportion was 65.02%. This study has certain guiding significance for the industrial production of functional Monascus.
