供氧对L-异亮氨酸分批发酵的影响

The Effect of Dissolving Oxygen on L Isoleucine Batch Fermentation

对黄色短杆菌L 异亮氨酸高产菌XQ 4 (AHVrAECrSucgSGrEthrα ABrIleHxr)分批发酵供氧需求进行了研究 .在 2L台式发酵罐中进行分批发酵 ,当体积传氧系数 (Kla)为 385h 1左右时 ,供氧比较适宜 ,在 138g/L的葡萄糖溶液中可产生 2 3.5 g/LL

The effect of dissolving oxygen on batch fermentation by Brevibacterium flavum L isoleucine producer XQ 4 (AHV r AEC r Suc g SG r Eth r α AB r IleHx r) was carried out. When Kla was 385 h 1 , the dissolving oxygen was suitable in 2 L fermentor. L isoleucine at the value of 23.5 g/L was accumulated in medium containing 138 g/L glucose.
