摘　　要：通过改进10m3种子罐的搅拌器,研究不同搅拌器对溶氧系数和谷氨酸高密度培养的影响。结果表明:由六弯叶圆盘涡轮搅拌器改造为六半圆叶圆盘涡轮搅拌器后,种子罐的溶氧系数是改造前的2.36倍,使谷氨酸菌高密度培养时的最终湿菌体量达到25.42%,是改造前的2.88倍。The effects of different stirrer on dissolved oxygen coefficient and high density culture of Glutamic acid bacterium were investigated by improving the stirrer of 10 m3 seeding tank. Taking six half round blade disk turbine stirrer instead of six tortile blade disk turbine stirrer, the dissolved oxygen coefficient of seeding tank was 2.36 times that of the original seeding tank, and the last wet cell concentration in high cell density culture of Glutamic acid bacterium reached 25.42%, which was 2.88 times t...
