- Fig. 1) must be based on the living conditions of the microorganisms 06, 08, 11 (shown in Fig. 2), which u. a. the maximum concentration of media components, the osmotic pressure and the pH. Thus, growth processes or metabolic production processes are due to the initial one
- composition of the compartments 02, 03 (shown in Fig. 1) limited.
- Type A compartments with type B compartments containing media components at a concentration outside of the living conditions of the microorganism allow, with sufficient mass transfer between them
- Type A and B compartments improved long term culturing. If the pH changes during the
- Type A compartments preferably added a buffer.
- Buffer capacity in the compartments of type A is limited, since too high a salt concentration for the
- Microorganism has a toxic or growth-inhibiting effect.
- the osmotic pressure limits the salt concentration in media. If a compartmented mixed population is used in which the second compartment class contains a buffer system in very high concentration and to a large
- Conditioned media can thus create the situation that a medium which is responsible for organisms of type A
- compartmentalized approach according to the invention can be two classes of compartments in one

- the invention provides an extraction strategy according to which the extractability into the dispersion medium is ensured by an enzymatic transfer of hydrophobic components to a substrate.
- a problem with biotechnological Production process is the isolation of the product.
- a bacteriological production step is combined with an enzymatic reaction which alters the product in its polarity so that products are selectively enriched in a compartment class or in the carrier phase.
