Interaction Of 3 Species Of Lactic Acid Bacteria And Optimization Of Mixed Culture Conditions
- Dec 13, 2018 -

The interaction between Streptococcu sthermophilus, Lactobacillus acidophilus and Lactobacillus casei was studied, and the culture conditions of mixed strains were optimized. The experimental results show that: the above 3 lactic acid bacteria have no antagonistic effect on each other, there is a promotion effect, and the metabolic products and strains of the synergistic effect of the related.

In the process of long-term experimental study and production practice, the limitation of single strain fermentation increasingly prominent, such as the elements are too complex or biochemical processes is mad not well fermentation, mixed fermentation by between strains can be complementary advantages, such as can get single strain fermentation cannot get some kind of product or improve production rate, increase the number of living bacterium, shorten the fermentation period, save production cost and so on, in order to solve the limitations of single strain fermentation opens up a new way.
