| 摘 要： | Candida krusei发酵生产甘油过程中，菌体生长由玉米浆限制，菌体对玉米浆的得率为1．63g/g，培养其中玉米浆浓度相同时，增加渗透压或通过流加补料限制生长阶段的菌体生长，可使甘油生产阶段的比耗糖速率减慢，比耗糖速率保持在不很高的水平，可以因消耗的葡萄糖用于生长，维持，甘油和副产物形成所占比例的变化而提高甘油得率。

| Abstract: | In the fermentation process of glycerol production, the growth of Candida krusei was limited by corn steep liquor (CSL) and the cell yield based on CSL was 1.63g/g. High osmotic environment or controlled cell growth in the growth phase caused decreased glucose consumption rate during the production phase. Higher glycerol yield was obtained at reduced glucose consumption rates due to a better distribution of metabolized glucose to growth, maintenance, and glycerol and by product formation. |

| Keywords: | Candida krusei glucose consumption rate osmotic pressure glycerol fermentation |
