摘要:
对草芽孢杆菌HB-32分批发酵过程中菌体细胞生长、3-羟基丁酮的形成以及葡萄糖的消耗随发酵时间的变 化规律进行研究。基于Logistic方程和Luedeking-Piret方程,建立3-羟基丁酮分批发酵过程中细胞生长、产物合成以 及基质消耗随时间变化的数学模型。对动力学模型的拟合曲线进行分析,发现模型的计算值能与实验值较好地拟 合,拟合模型R2均大于0.98,表明建立的动力学模型能较好地反映3-羟基丁酮分批发酵过程。

Abstract:
The cell growth of acetoin accumulation and glucose consumption by Bacillus subtilis HB-32 throughout the batch fermentation were investigated and corresponding kinetic models were proposed according to Logistic and Luedeking- Piret equations. The results showed that the predicted values by the models were in good agreement with the measured values, indicating that the models could provide a reasonable description for the acetoin bath fermentation.
Key words: Bacillus subtilis, acetoin, bath fermentation, fermentation kinetic models
