摘要:

利用Box-Benhnken 中心组合设计和响应面法优化乙醇提取酿酒酵母胞内谷胱甘肽的条件。结果表明,谷胱甘肽最佳提取条件为乙醇体积分数43.7%、乙醇添加量7.03mL/0.1g 干酵母粉、抽提时间80min、谷胱甘肽提取率达最大为9.54mg/g。

关键词: 谷胱甘肽, 乙醇, 酿酒酵母, 响应面分析

Abstract:

Box-Behnken design and response surface methodology were applied to maximize the glutathione yield from Saccharomyces cerevisiae extracted with alcohol. Results showed that the optimum conditions of glutathione extraction were as follows: ethanol concentration 43.7%, amount of added ethanol 7.03 mL/ 0.1 g yeast powder and extraction time 80 min. Under such optimal conditions, a maximal glutathione yield of 9.54 mg/g were obtained.

Key words: glutathione, ethanol, Saccharomyces cerevisiae, response surface analysis
