Carbon dioxide from fermentation can be captured at a relatively low cost, requiring only dehydration and compression. Unlike other CO 2 point sources, ethanol production generates a high purity (99%) stream of fermentation CO 2 containing only CO 2, H 2 O, and small amounts of sulfur and organic compounds.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.
