20 L fermentor i pilot

20L Fermentor

A 20L fermentor is used to carry out biofermentation processes on a pilot scale, which falls between laboratory and industrial scale.

The fermentation process can be applied to a wide range of products beyond food, such as chemicals and pharmaceutical products. Biomass, consisting of, for example, microorganisms or plant material, is converted using, for example, yeast or bacteria.

In a biofermentation process, biotechnology is used to select, modify, and optimize microorganisms to produce specific biosolutions. In biofermentation processes, it is the task of biotechnology to utilize microorganisms such as bacteria, yeast, fungi, or plant cells to manufacture desired biosolutions.

Additionally, biotechnology can be used for the development and optimization of the fermentation process by monitoring and controlling growth conditions to achieve high yields and quality of biosolutions.

The biofermentation process can produce a wide range of biosolutions for industries such as food production, biochemical production, and pharmaceutical production.
