Fermentation from corn-ethanol plants is the largest single-sector CO2 source for the U.S. merchant gas markets.“There are many challenges to overcome before arriving at an industrial process that can turn carbon dioxide into usable ethanol,” said Brookhaven chemist José Rodriguez, who participated in the work. “For example, there needs to be a clear way to improve the selectivity towards ethanol production.Crop production accounts for 50 percent of the total emissions from ethanol production. One-half of these emissions are in the form of nitrous oxide (N2O.) Nitrous oxide is a very powerful GHG (289 times as powerful as carbon dioxide.) So a small amount of nitrous oxide has a powerful GHG impact.

Going from pyruvate to ethanol is a two-step process. In the first step, a carboxyl group is removed from pyruvate and released in as carbon dioxide, producing a two-carbon molecule called acetaldehyde. In the second step, NADH ‍ passes its electrons to acetaldehyde, regenerating NAD + ‍ and forming ethanol.
