Illuminated Bacteria Enlighten Biofuel Production

Illuminated Bacteria Enlighten Biofuel Production

Because of their prolific photosynthesizing, cyanobacteria have great potential for solar-powered biofuel production. To tap into that potential, researchers from Queen Mary’s School of Biological and Chemical Sciences recently became the first to visualize and control the “biological electrical switch” that dictates how electrons flow through the bacterium. But what does manipulating electron flow have to do with biofuel? “In chemical terms, fuels are just sources of electrons,” explains Conrad Mullineaux, professor of Microbiology at Queen Mary and study co-author. “So where the electrons go in the cell is vital for fuel production.” To witness the electron movement, the team used fluorescent labeling to mark certain electron-carrying proteins. These proteins are an integral part of how the cell generates energy, and a better understanding of how they work will be essent...
