摘要:
采用带溶氧电极的摇瓶对谷氨酸发酵过程进行研究,结果表明,只有对发酵过程(特别是生产期)的溶氧严加控制,才有可能得到谷氨酸高产。在装液量为30ml,摇床转速为160-180r/min,发酵中期溶氧水平8-10%时,谷氨酸产率6.56%,糖酸转化率55%。当采用pH和溶氧为标准补尿时,所得pH曲线及溶氧曲线不完全一致,但产酸率很接近,说明溶氧曲线至少可以作为补尿及判断发酵终点的依据之一。
Abstract:
The fermentation of glutamic acid (GA) was investigated by adopting shaking flask with dissolved oxygen (DO) electrode. The results reveal that a high yield of GA can be obtained only if the dissolved oxygen in fermentation especially during the productio
