| 摘 要： | 以玉米粉为碳源,添加一定量的豆粕粉和玉米浆干粉进行鼠李糖乳杆菌L-乳酸发酵,利用均匀设计法对培养基进行优化.结果表明当玉米粉、豆粕粉、玉米浆干粉的浓度分别为150 g/L、19.4 g/L、50g/L时,发酵所得L-乳酸的浓度达到最大值142.1 g/L,乳酸转化率为92.5％.

| Abstract: | L-lactic acid fermentation by Lactobacillus casei subsp.rhamnosus was studied with the corn powder as carbon source.Some soybean meal powder and corn steep powder was added to improve the production of L-lactic acid.According to the uniform design,the optimum dosages of corn powder,soybean meal powder and corn steep powder in culture media were 150 g/L,19.4 g/L and 50 g/L,respectively,under which the maximum concentration and yield of L-lactic acid were 142.1 g/L and 92.5%,respectively. |
