Microbial Electrosynthesis: Feeding Microbes Electricity To Convert Carbon Dioxide and Water to Multicarbon Extracellular Organic Compounds
The possibility of providing the acetogenic microorganism Sporomusa ovata with electrons delivered directly to the cells with a graphite electrode for the reduction of carbon dioxide to organic compounds was investigated. Biofilms of S. ovata growing on graphite cathode surfaces consumed electrons with the reduction of carbon dioxide to acetate and small amounts of 2-oxobutyrate. Electrons appe...
متن کاملPowering microbes with electricity: direct electron transfer from electrodes to microbes.
The discovery of electrotrophs, microorganisms that can directly accept electrons from electrodes for the reduction of terminal electron acceptors, has spurred the investigation of a wide range of potential applications. To date, only a handful of pure cultures have been shown to be capable of electrotrophy, but this process has also been inferred in many studies with undefined consortia. Poten...
متن کاملEmerging electrochemical and membrane-based systems to convert low-grade heat to electricity
Low-grade heat from geothermal sources and industrial plants is a significant source of sustainable power that has great potential to be converted to electricity. The two main approaches that have been extensively investigated for converting low-grade heat to electrical energy, organic Rankine cycles and solid-state thermoelectrics, have not produced high power densities or been cost-effective ...
متن کاملEnhancement of survival and electricity production in an engineered bacterium by light-driven proton pumping.
Microorganisms can use complex photosystems or light-dependent proton pumps to generate membrane potential and/or reduce electron carriers to support growth. The discovery that proteorhodopsin is a light-dependent proton pump that can be expressed readily in recombinant bacteria enables development of new strategies to probe microbial physiology and to engineer microbes with new light-driven pr...
متن کاملEngineered Fluorescent Proteins Bring Biochemistry To Light
To ensure the continued advancement of cell biology, it is critical that the visualization of biochemical activities in live model animals with high temporal and spatial resolution ceases to be a technical tour de force, and instead becomes a routine and widely accessible endeavor. In the last decade a convergence of interests between physicists, chemists, biologists, and engineers has resulted...
