摘要
本实验对酿酒酵母(Saccharomyces cerevisiae)CS10515产谷胱甘肽的培养条件进行了初步研究,确定了其最佳培养基组成为:葡萄糖为5%、酵母膏1.2%、硫酸铵0.6%、硫酸镁0.02%、磷酸二氢钾0.1%;当发酵液初始pH为6.0、装液量50%～60%、振荡速度300r/min时,经过24h振荡培养后,谷胱甘肽的产量为90.20mg/L。
The production condition for glutathione by Saccharomyces cerevisiae CS10515 was investigated. The results showed that the medium composition was that, glucose 5%, yeast extract 1.2%, （NH4）2SO4 0.6%, MgSO4 0.02%, K2HPO4 0.1%. The optimal conditions for producing glutathione occured at initial pH6.0, broth volume 50%～60% and rotational speed 300 r/min. After 24 hours fermentation, the glutathione produced by Saccharomyces cerevisiae was 90.20 mg/L.
