嗜酸乳杆菌促生因子的研究

Research on the growth-promoting factors of Lactobacillus acidophilus

以11%的脱脂乳为基础培养基,研究了加入几种不同类型、不同比例的促生因子对嗜酸乳杆菌产酸及凝乳的影响。结果表明,葡萄糖0.75%、吡哆醛0.09%、半胱氨酸1%、酪蛋白水解物0.5%对嗜酸乳杆菌生长促生作用的影响较大。

Using 11% skimmed milk as basic medium, the effects on acid-production and milk-curding of Lactohacillus acidophilus were studied by the addition of different kinds and amounts of growth-promoting factors. The results showed that 0.75% glucose, 0.09% pyridoxal, 1% cysteine, and 0.5% casein hydrolysate have more positive effects on the growth of L. acidophilus.
