In the fermentation process, there are usually two types of fermentation: triangular flask fermentation and fermenter fermentation. Triangular flask fermentation is experimented in the pre-fermentation stage. So what exactly is the difference between two ways?
1. The difference between triangular flasks and fermenters
Fermentation tank is by mechanical stirring, the shear force for the strain is larger, and the damage of the bacterium is much greater than the triangle flask.
The fermentation tank can control the air passed in, and through stirring and aeration, the liquid and air are mixed evenly, and the dissolved oxygen parameters can be controlled.
The pH of fermentation tank is adjusted by adding acid and alkali through direct flow, which can control its value within the set range.
Triangles can obtain experimental fermentation data more quickly under conditions such as limited space. However, fermenters are more accurate in the fermentation experimental data obtained because of their good confinement and controllable fermentation parameters. Triangular flask fermentation is also mainly to provide reference data for subsequent in-tank fermentation. Due to the different strain types, the fermentation method needs to be determined on a case-by-case basis.
