溶氧量对以玉米培养基流加培养生产酵母的影响

Effect of Dissolved Oxygen on Fed-batch Culture of Yeast in Maize-containing Media

摘要:

本文通过以玉米为培养基流加培养生产酵母过程中，用控制通氧的方法研究溶氧量对酵母细胞浓度和酵母细胞生长速率的影响，得出通氧量的控制与酵母生长的关系。结论为：溶氧量达到50%的时候，酵母细胞产率最大，达到38%。

Abstract:

The effect of dissolved oxygen on the concentration of yeast cells in fed-catch culture was studied with maize as raw culture materials. Results showed that the yield of yeast reached 38% when 50% dissolved oxygen was used in the process of fed-batch culture.
