摘要:通过酿酒酵母工程菌(Saccharomyces cerevisiae 1211)发酵制备青蒿酸,并通过单因素实验和响应面优化,
考察了发酵温度、pH、半乳糖质量浓度、发酵碳源及发酵氮源等对青蒿酸发酵产量的影响。结果表明:在发酵
温度 30 ℃,发酵培养基初始 pH=5.5,发酵培养基中蔗糖质量浓度 91.8 g/L,半乳糖质量浓度 10.1 g/L,硫酸铵
质量浓度 10.3 g/L,磷酸二氢钾质量浓度 8.7 g/L 的条件下,青蒿酸发酵产量可达(1529.7±12.6)mg/L,与未优
化时的发酵产量相比,提升了 67.1%。

Abstract: The fermentation medium and conditions of artemisinic acid produced by engineered S.
cerevisiae 1211, were optimized in this paper. The yield of artemisinic acid was used as evaluation index to
investigate the effects of temperature, pH, carbon source, nitrogen source and galactose concentration on
the fermentation process by using single factor experiments and response surface methodology.The results
showed that the production of artemisinic acid could reach (1529.7±12.6) mg/L under the conditions of
temperature 30 ℃, pH=5.5, sucrose 91.8 g/L, galactose 10.1 g/L, ammonium sulfate 10.3 g/L and
monopotassium phosphate 8.7 g/L, which was increased by 67.1% compared with that in the initial medium.
This study provided some reference for the further development of industrial production.
