Caption: UC Davis graduate student Gabriel Rodriguez, left, and Shota Atsumi, assistant professor of chemistry sample a culture of E. coli engineered to produce a sweet-smelling ester. Esters are key to the $20 billion-a-year scents and flavorings industry, but almost all are currently derived from oil and gas. New technology invented at UC Davis allows specific esters to be made by microbes.
