The disclosure relates to a container for filtering a suspension which comprises a lid and a vessel. The container comprises a filter that divides an interior space of the container into a first compartment and a second compartment. The lid comprises a first access and a second access. The first access is connected to the first compartment, and the second access is connected to the second compartment.

Container and method for filtering a suspension

Reactor plant and process for culturing phototropic microorganisms with a reactor vessel and a photosynthetic module, which are connected with one another in a circulation circuit by a pump and can be controlled via a control unit, where in the circulation circuit or in the reactor vessel, a homogenizer is provided, where a light-intensity control of the photosynthetic module is provided, and where a bypass of the circulation circuit or of the reactor vessel with a filter device which is arranged externally of the reactor vessel for separating off extracellular products during the fermentation is provided.

Reactor plant and process for culturing phototropic microorganisms

Disclosed are a method and a device for the biotechnological production of valuable products, in which a medium is fed to a bioreactor and is subjected to a fermentation process, the valuable product is gathered as a filtered permeate and/or concentrated retentate via a cross-flow filtration system that is mounted downstream thereof, and residues are once again fed to the bioreactor until being gathered as a retentate. Other materials can be fed to the bioreactor in a controlled manner in addition to the medium while the concentrated retentate and permeate can be gathered in a controlled manner. The fermentation process and the filtration process are regulated in a synchronized manner in an integrated system via a digital control unit.

Method for the biotechnological production of valuable products

A bioreactor for culturing microorganisms which has a reactor vessel, a plurality of gas-introduction tubes and a gas-introduction system for introducing gas into a culture medium in the gas-introduction tubes via injectors, wherein the gas-introduction tubes are connected by their respective lower end, in the vertical direction, to the reactor vessel and by their opposite upper end to the upper end of an upright vessel which is likewise connected by its lower end to the reactor vessel, and at the upper end of the upright vessel an expansion vessel is arranged.

Bioreactor for culturing microorganisms

A device and a method for the cultivation of cells is disclosed that utilizes external pneumatic pressure responsive to liquid level sensors to gently recirculate and cause turbulence in cell growth medium to promote cell growth without any shearing action and without a stir motor or mechanical manipulation means.
