乳酸是一种重要的化工原料，具有广泛的工业应用前景，发酵法生产乳酸效率高，凝结芽孢杆菌表现出优良的发酵性能。甜菜碱是一种有效的乳酸发酵保护剂。甜菜碱对B.凝结物被发现。甜菜碱可以通过保护l-LDH活性和细胞生长免受渗透抑制来提高乳酸产量，特别是在高葡萄糖浓度和有机氮营养不足的情况下。添加0.05g/L甜菜碱的发酵液乳酸产量比不添加甜菜碱的发酵液高17.9%。利用甜菜糖蜜中富含的蔗糖和甜菜碱进行混合补料发酵，使产率提高了22%。B高效乳酸发酵。因此，通过使用甜菜碱和甜菜糖蜜开发了凝结多糖。
Lactic acid is an important chemical with various industrial applications, and it can be efficiently produced by fermentation, in which Bacillus coagulans strains present excellent performance. Betaine can promote lactic acid fermentation as an effective osmoprotectant. Here, positive effect of betaine on fermentation by B. coagulans is revealed. Betaine could enhance lactic acid production by protecting l-LDH activity and cell growth from osmotic inhibition, especially under high glucose concentrations and with poor organic nitrogen nutrients. The fermentation with 0.05 g/L betaine could produce 17.9% more lactic acid compared to the fermentation without betaine. Beet molasses, which is rich in sucrose and betaine, was utilized in a co-feeding fermentation and raised the productivity by 22%. The efficient lactic acid fermentation by B. coagulans is thus developed by using betaine and beet molasses.
