The present invention provides a device comprising a first chamber and a second chamber, the first chamber oriented in two alternative ways (1) the first chamber having an anode in contact with an aqueous solution comprising a photosynthetic organism or photosynthetic part thereof and an electron acceptor molecule, an inlet and an outlet, OR (2) the first chamber having direct contact between an anode and the photosynthetic organism, the second chamber having a cathode in contact with an aqueous solution of an electrolyte, an outlet, wherein the anode and the cathode are connected by a switched electric circuit optionally having an external power source and wherein the second chamber is separated from the first chamber by a proton selective membrane. The device described in the present inventions allows for the production of hydrogen and electrical current.
A device for the generation of hydrogen by oxygenic photosynthesis comprising a first chamber and a second chamber, the first chamber having two arrangements in which either (1) the first chamber has an anode in contact with an aqueous solution comprising a photosynthetic organism and optionally an electron acceptor molecule, or a photosynthetic part of said photosynthetic organism and an electron acceptor molecule, an inlet and an outlet, or (2) the first chamber has an anode in direct contact with a photosynthetic organism, the second chamber having a cathode in contact with an aqueous solution of an electrolyte under anaerobic conditions, an outlet for the release of hydrogen, wherein the anode and the cathode are connected by a switched electric circuit having an external power source to supply a bias potential and wherein the second chamber is separated from the first chamber by a proton selective membrane, in which hydrogen is produced on application of light to the first chamber by reduction of hydrogen ions to hydrogen gas.
A device for the generation of electric current by oxygenic photosynthesis comprising a first chamber and a second chamber, the first chamber having two arrangements in which either (1) the first chamber has an anode in contact with an aqueous solution comprising a photosynthetic organism and optionally an electron acceptor molecule or a photosynthetic part of said photosynthetic organism and an electron acceptor molecule, an inlet and an outlet, or (2) the first chamber has an anode in direct contact with a photosynthetic organism, the second chamber having a cathode in contact with an aqueous solution of an electrolyte under aerobic conditions, an outlet, wherein the anode and the cathode are connected by a switched electric circuit and wherein the second chamber is separated from the first chamber by a proton selective membrane, in which electric current is generated on application of light to the first chamber by reduction of oxygen to water at the cathode.
