Abstract
The invention relates to a method for extracting oxygen form a reaction chamber, as well as a use of microorganisms in such a method and a photobioreactor for carrying out the method. According to the invention, the method comprises the steps—irradiating at least one phototropic microorganism with light under anaerobic conditions in a reaction chamber, and—in situ bonding of produced oxygen by means of the microorganism by oxidation of an oxygen-utilizing substrates.
Claims11
A method for the bioreactive extraction of produced oxygen from a reaction chamber, comprising the following steps:
- irradiating at least one phototropic microorganism under anaerobic conditions in a reaction chamber, and
- in situ bonding of produced oxygen by means of the microorganism by oxidation of an oxygen-utilizing substrate.
A use of phototropic microorganisms which, in addition to hydrogenases, nitrogenases or oxidoreductases, as hydrogen-producing enzyme, additionally have or produce oxidoreductases as oxygen-converting enzymes, for obtaining hydrogen (H2) or methanol and oxygen (O2) from water or aqueous liquids and solutions and for simultaneous in-situ removal of the oxygen (O2) using corresponding substrates which form products with the oxygen.
A photobioreactor comprising the genetically modified cyanobacterial strain Synechocystis sp. PCC6803 which has or produces the alkane monooxygenase enzyme system AlkBGT.
