| 摘 要： | 通过对乳酸菌复合系SFC-2培养基的组分进行响应面优化，从而得出SFC-2优化培养基配方为白砂糖10g／L、蛋白胨31．36g／L、牛肉膏15．57g／L、酵母膏10g／L、乙酸钠7．3g／L、柠檬酸三铵4g／L、KzHP044g／L、MgS04·7H200．58g／L、MnSO4·H200．25g／L。SFC-2在此培养基中经30℃，16h培养，其活菌数可达到4．0×10^8cfu／mL，较MRS-S中（8．2×10^7cfu／mL）提高近5倍。

| Abstract: | The medium components for LAB community SFC-2 were optimized by response surface meth- odology,which contained white granulated sugar 10 g/L,peptone 31.36 g/L,beef extract 15.57 g/L,yeast extract 10 g/L,sodium acetate 7.3 g/L,triammonium citrate 4 g/L,K2 HPO4 4 g/L,MgSO4 · 7H2O 0. 58 g/L,MnSO4 · H2O 0.25 g/L. After cultivation in optimization medium for 16 h at 30 ℃ ,the viable count of SFC-2 was 4.0 × 10a cfu/mL, which was about 5 times higher than that in MRS-S（8.2 × 107 cfu/mL）. |
