Methane production using nitrogen-fixing bacterium

Researchers report an engineered strain of the photosynthetic bacterium Rhodopseudomonas palustris that uses a remodeled variant of the nitrogenase enzyme, which converts nitrogen gas to ammonia, to reduce carbon dioxide to methane using light energy, demonstrating the feasibility of using light-powered microbes to generate energy-rich hydrocarbons from carbon dioxide in a single enzymatic step. - Read at PNAS.org
