Pre culture

Starting with a preserved strain, the microorganisms are multiplied in several steps on laboratory scale. Multiplication takes place in specially adapted sterile culture media under optimal conditions.

Main culture

The prepared pre cultures are then inoculated with sterile culture media in a bioreactor and multiplied on a large technical scale in bioreactors under optimal conditions.


Towards the end of the reproduction phase, the microorganism are separated from the supernatant through centrifugation and mixed with protective substances.


The subsequent freeze-drying of the harvested biomass takes place in the hygiene room with filtered air, laminar flow cabin and controlled air humidity.

The finished product after freeze-drying is called lyophilisate. This has to be finely ground. Individual batches of the same strain are subsequently homogenized by mixing and packed. A safe and successful process is ensured by using the best technical equipment and building on our comprehensive technological and microbiological knowledge.
