摘要
目的:研究不同类型载气对于汽提发酵的影响。方法:分别二氧化碳和氮气作为汽提载气,测定不同通气量(0.2m3/h、0.4m3/h、0.6m3/h)下细胞的生长。结果:相比二氧化碳,以氮气作为载气,细胞生长速度提高1.3倍左右;而且随着通气量增大,这种现象更明显。结论:氮气更适宜作为汽提发酵的载气。
Objective：The effect of different types of gases on stripping fermentation was studied.Method：The cell growth with different gas flux（0.2m^3/h,0.4m3/h,0.6m^3/h）was determined by nitrogen and carbon dioxide,respectively.Result：Cell grows 1.3 times faster by nitrogen dioxide than by carbon dioxide.With the increase of gas flux,this phenomenon is more obvious.Conclusion：In comparison with carbon dioxide,nitrogen is more favorable for stripping fermentation.
