摘　　要：相对于一般的发酵系统,利用两相系统转化植物甾醇为雄烯二酮可以改善植物甾醇的溶解性,提高其转化率。文中研究了有机相的种类,有机相在发酵液中所占的比例,植物甾醇的投料量对植物甾醇转化率的影响,得到了最佳工艺条件:当有机相为大豆油、有机相所占比例为22%、投料量为4g/L时,植物甾醇的转化率最高,达到85.7%。Compared with general system for fermentation, two-phase systems can improve the solubility of phytosterol and transformation rate in the process of the transformation of phytosterol into androst-4-ene- 3,17-dione. The variety of organic-phase, the quantity of phytosterol, and the rate of organic-phase in fermentation system on the transformation rate were discussed. The best processing technology was obtained. When the organic-phase is soybean oil, the rate of organic-phase in fermentation system is 22%, the quantity of phytosterol is 4g/L, the transformation rate of phytosterol reached 85.7%.
