Over a decade ago, researchers at UC Davis noticed something unusual while studying yeast: tiny oil droplets sinking to the bottom of a flask. The strain of yeast was producing a natural compound with soap-like properties, and now it’s being developed as an ingredient in cleaning products that are gentle on skin and environmentally friendly.

A popular species of yeast that’s used to make beer, bread and wine is also contributing to the food industry in a different way – improving food safety. A yeast strain from the UC Davis Phaff Yeast Culture Collection is being used commercially to remove a toxic compound from fried and baked foods.
