本文对Lactobacillus thermophilus（T-1）的5L罐L-乳酸发酵过程进行了研究，并建立了菌体生长，底物消耗及产物生成动力学模型。经验证，模型的理论值和实验值拟和较好。所建动力学模型对反应器设计、工艺原理以及有效的控制发酵过程具有指导意义。

The kinetic models of cell growth, product formation, and substrate fermentation were established. It showed that the theoretic values of the models and the experimental data were in a good agreement. The kinetic models were helpful to practical reactor design, craft management and control of fermentation process.
