In microbial fermentation production, microorganisms can only grow and reproduce normally under a suitable environment in addition to the composition and concentration of the medium.
1.PH
In the process of microbial fermentation, the influence of the cultivation environment is very significant. Among them, the pH value of the solution is a very important control index. The pH value plays a significant role in promoting and inhibiting the metabolism, growth, and reproduction of microorganisms by affecting the activities of various enzymes. Therefore, the difference in pH value will directly affect the synthesis and growth of microorganisms and change the use and absorption of nutrients by microorganisms.
2. Temperature
The enzymatic activity is directly related to the control of temperature, and the enzymatic activity of microbial cells will be significantly damaged under a high-temperature environment, and the proteins in microbial cells are easily concentrated or degraded at high temperatures. Low temperature has an important inhibitory effect on the growth of microorganisms. The growth temperature of different kinds of microorganisms varies with the different stages of product synthesis. Other fermentation conditions and factors, such as the composition of the medium, should be considered when designing the fermentation temperature. If necessary, energy consumption, fermentation cycle, yield level, and culture temperature can be considered.
3. Dissolved oxygen
One of the key factors for the growth of aerobic microorganisms is the demand for oxygen, and aerobic bacteria can only maintain normal metabolism in an environment of sufficient oxygen to promote their growth. Insufficient aerobic oxidation processes by microorganisms may affect the pH of the fermentation broth, produce toxic substances, and affect bacterial growth and product production. By regulating ventilation, the oxygen supply can be effectively controlled and guaranteed. Decomposition fermentation can reduce the amount of liquid, increase the speed of fermentation, effectively increase the amount of oxygen, and greatly improve the production capacity of bacteria. The corresponding experimental results show that dissolved oxygen has a positive effect on the synthesis of the product.
Innova fermenters can precisely control PH, Temperature, and DO (Dissolved oxygen), provide a suitable fermentation environment, and create perfect fermentation conditions, which could help get maximize fermentation products.
