| 摘 要： | 红曲霉生长过程中分别添加酵母破壁液、酵母和酵母乏液,均能提高MonacolinK的产量,其相应的MonacolinK产量分别为48.06、43.64和44.79mg/L,是对照的1.38、1.26、1.29倍。当在红曲霉发酵初始添加酵母破壁液、添加量为2.7%(v/v),MonacolinK的产量可达61.93mg/L。通过发酵过程中菌体量变化的观察,发现添加酵母破壁液的主要作用是提高菌体量和改善红曲霉的代谢,进而提高MonacolinK的产量。

| Abstract: | During the fermentation of Monascus, adding yeast lysate, yeast and yeast broth filtrate can improve the yield ofMonacolin K. The Monacolin K yield is 48.06, 43.64 and 44.79mg/L respectively, compared to Monascus cultivate withoutinducer, increase 1.38, 1.26 and 1.29 times respectively. Adding Yeast lysate in the beginning of Monascus fermentation byquantity 2.7%(v/v), the yield of Monacolin K reaches 61.93mg/L. Study on variance of Monascus biomass show yeast lysatecould improve the biomass of Monascus and metabolize pathway, so increase the yield of Monacolin K. |
