摘要
结合酵母细胞酶促合成ATP的活性测试,在5L发酵罐中培养啤酒酵母,考察了通气对菌体生长和细胞活性的影响。实验结果表明:通气量的变化,对菌体的生长速度和得率具有明显的调节作用;采用氧限制方法培养的啤酒酵母用于ATP生产时得率可达到100%。通气量6.0L/(L·h)时培养的酵母细胞用于ATP生产的效率比在通气量60L/(L·h)下培养的酵母细胞提高50%以上。
The effect of aeration rate was studied in the culture of brewer's yeast used for ATP production. Under aerated condition, the yeast growth rate and growth yield were enhanced. The yeast cell activity for the ATP production increased at oxygenlimited conditions. These results indicate that aeration plays an important role in yeast metabolism and physiology.
