“At fermentere” stammer fra latin og betyder “at bringe til gære”.

1L fermentor

The 1L fermentor is suitable for research, development, and optimization of biofermentation processes before scaling up to a larger scale. A 1L fermentor is used to carry out biofermentation processes on a laboratory or smaller scale.

The fermentation process can be used for a wide range of products beyond food, such as chemicals and pharmaceutical products. The fermentation process involves converting biomass, such as microorganisms or plant material, using yeast or bacteria. A 1L fermentor allows for the creation and control of optimal conditions for this process.

In a biofermentation process, biotechnology is used to select, modify, and optimize microorganisms to produce specific biosolutions. In biofermentation processes, biotechnology's role is to utilize microorganisms such as bacteria, yeast, fungi, or plant cells to produce a desired biosolution.

Additionally, biotechnology can be used to develop and optimize 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 within industries such as food production, biochemical production, and pharmaceutical production.
