Professor Carrie Harwood and colleagues have engineered a bacterium that can take carbon dioxide from the air and turn it into fuel in a single enzymatic step. The process draws on sunlight to produce methane and hydrogen inside the bacterium Rhodopseudomonas palustris, in essence reversing combustion. These engineered bacteria could guide scientists toward better carbon-neutral biofuels. Read more about the research here. The full paper is published in the September 22, 2016, edition of PNAS.
