A process for the extraction bioreactive oxygen produced from a reaction chamber, as well as use of phototrophic micro organisms in the production of hydrogen

The invention relates to a process for extracting oxygen from a reaction chamber, and to the use of microorganisms in such a method, and a photo bioreactor for carrying out the Verfahrens.Erfindungsgemas the method comprising the steps of - exposing at least one phototrophic microorganism with light under anaerobic conditions in a reaction chamber and - in situ binding of nascent oxygen by the microorganism by oxidation of an oxygen-utilizing substrate.
