玉米制糖发酵生产L-乳酸的工艺优化

L-乳酸工业化生产过程中,原料玉米糖水品质和发酵菌种性能是影响发酵效果的主要因素。通过对玉米制糖和发酵工艺整合优化,选育高性能L-乳酸菌种,并进行发酵过程调控,既能有效提升玉米原料利用率,又能实现乳酸高效发酵,提升L-乳酸光学纯度。本文对玉米原料发酵生产L-乳酸的关键工艺技术进行分析,期望能为后续工业生产提供参考。

Optimization of L-lactic Acid Production by Corn Sugar Fermentation

In the industrial production of L-lactic acid,the quality of corn syrup and the performance of fermentation strains are the main factors that affect the fermentation effect.Through the integration and optimization of corn sugar production and fermentation process,high-performance L-lactic acid strains were selected,and the fermentation process was regulated,which can not only effectively improve the utilization rate of corn raw materials,but also achieve highefficiency fermentation of lactic acid,and improve the optical purity of L-lactic acid.Based on the analysis of the key technology of L-lactic acid production by corn fermentation,this paper hopes to provide a good reference for the follow-up industrial production.
