Teaching yeast new tricks
Gevo is another company which intends to enter the jet fuel business longer term but in the near term plans to make isobutanol from cornstarch. It's a chemical "building block" used in the production of many products such as rubber, paints, and plastics. Its process uses genetically modified yeast with metabolic pathways that secrete isobutanol molecules rather than alcohol (ethanol) during fermentation. Its goal is to retrofit corn ethanol plants, using essentially the same equipment.
