溶氧控制和pH控制在赖氨酸分批发酵过程中的应用

The Application of Dissolved Oxygen and pH Control in Lysine Fermentation

摘要:

研究了溶氧和ｐＨ值对赖氨酸产生菌ＦＢ４２发酵的影响，结合发酵过程的动力学分析，得出了分批发酵操作的溶氧和ｐＨ控制模式。结果表明两种控制都使发酵水平得到提高，但以溶氧控制更有效，在溶氧控制模式下，发酵的转化率从３３．６％提高到３８．１％。

Abstract:

The influence of dissolved oxygen and pH on lysine fermentation by Brevibac-terium flavmn FB42 in batch process was studied.By means of controlling Kla,dissolvedoxygen tension was controlled.Aimed with kinetic analysis of fermentation process,the Kla cont
