Abstract

The invention relates to a method and a device for series cultivation of organisms which is particularly suitable for providing organisms to be cultivated with a culture medium that has a toxic effect on said organisms at a high dosage, but when applied in appropriate dosage, said device determines the amount of substrate required to enable organisms to produce substances microbially in optimum conditions. According to the invention, a dosing schedule is predefined and the amount of substrate in the flask is adjusted according to actual requirements. In order to avoid underdosage, filling of the shaking flask no longer occurs according to a fixed predefined sequence.
