A process for cultivation of photoautotrophic microorganisms is proposed comprising
providing a photosynthesis layer (2) containing a photosynthesis medium and photoautotrophic microorganisms suspended therein in a closed inclusion space with an outer border (1) restricting gas diffusion, whereat the photosynthesis layer exhibits a mean thickness of not more than 10 mm,exposing the photosynthesis layer (2) to light without whirling a gas within or piping a gas through the photosynthesis medium under restriction the of the diffusive gaseous exchange between the inclusion space with the surrounding, whereat the supply of the microorganisms with bicarbonate ions is realized by storage of bicarbonate ions in the photosynthesis medium and/or delivery of a photosynthesis substrate in the kind of carbon dioxide and/or bicarbonate from a cell free carbon storage medium (4) localized outside of the photosynthesis medium, andchanneling away the gas volume formed at photosynthesis. Further a photobioreactor for the cultivation of photoautotrophic microorganisms is proposed, that comprises an closed inclusion space with outer border restricting gas diffusion, whereat the inclusion space exhibitsa first compartment for the design of a photosynthesis layer (2) with a thickness of not more than 10 mm, andat least one second compartment for the inclusion of a photosynthesis layer that is separated from the first compartment by a least one membrane which is permeable to a substrate of photosynthesis chosen from the group comprising carbon dioxide or bicarbonate. |
