Microbial electro-photosynthesis

Title: Microbial electro-photosynthesis

Abstract

Methods and apparatus for growing photosynthetic organisms lacking Photosystem II (PSII) function using externally supplied electrons shuttled into the organism using redox mediators to improve photosynthetic output and to produce and recover chemicals of interest. By removing PSII, all PAR photons are funneled toward Photosystem I, thereby significantly increasing the theoretical photon utilization efficiency for CO2 fixation, energy storage and the capacity to synthesize valuable chemicals. Additional genetic modification can be performed to insert or enhance specific metabolic pathways to generate products of commercial interest.

Polymer-hybrid electro-optic devices and method of fabricating polymer-hybrid electro-optic devices

Patent Ocola, Leonidas E.; Gosztola, David J.; Yanguas-Gil, Angel

A polymer-hybrid electro-optic device is fabricated by providing a semiconductor substrate, depositing a metal electrode layer on the semiconductor substrate, depositing a dielectric barrier core layer within a gap of the metal electrode layer, patterning a polymer layer to cover the dielectric barrier core layer and partially covering the metal electrode layer, infiltrating the polymer layer with an inorganic component to form a hybrid oxide-polymer layer, and removing excess inorganic component from the semiconductor substrate and metal electrode layer.

Stabilization of rubisco activase for enhanced photosynthesis and crop yields

Patent Pokkuluri, Phani R.; Schiffer, Marianne; Joachimiak, Andrezej; ...

A modified rubisco activase, wherein the modified rubisco activase has a melting temperature greater than that of wild type rubisco activase. Further aspects of the disclosure relate to an isolated polynucleotide encoding a modified rubisco activase and a recombinant expression system comprising the isolated polynucleotide. Still further aspects of the disclosure relate to a plant cell transfected with the recombinant expression system. Certain aspects of the disclosure relate to a genetically modified plant expressing the isolated polynucleotide encoding a modified rubisco activase.

Method for improving product yields in an anionic metalloporphyrin-based artificial photosynthesis system

Patent Shelnutt, John A [Albuquerque, NM]

A method for improving product yields in an anionic metalloporphyrin-based artificial photosynthesis system for hydrogen generation which comprises forming an aqueous solution comprising an electron donor, methylviologen, and certain metalloporphyrins and metallochlorins, and irradiating said aqueous solution with light in the presence of a catalyst. In the photosynthesis process, solar energy is collected and stored in the form of a gas hydrogen. Ligands attached above and below the metalloporphyrin and metallochlorin plane are capable of sterically blocking photochemically inactive electrostatically bound .pi.--.pi. complexes which can develop.

Self-assembled photosynthesis-inspired light harvesting material and solar cells containing the same

Patent Lindsey, Jonathan S [Raleigh, NC]; Chinnasamy, Muthiah [Raleigh, NC]; Fan, Dazhong [Raleigh, NC]

A solar cell is described that comprises: (a) a semiconductor charge separation material; (b) at least one electrode connected to the charge separation material; and (c) a light-harvesting film on the charge separation material, the light-harvesting film comprising non-covalently coupled, self-assembled units of porphyrinic macrocycles. The porphyrinic macrocycles preferably comprise: (i) an intramolecularly coordinated metal; (ii) a first coordinating substituent; and (iii) a second coordinating substituent opposite the first coordinating substituent. The porphyrinic macrocycles can be assembled by repeating intermolecular coordination complexes of the metal, the first coordinating substituent and the second coordinating substituent.
