qWhat do beer, bread, wine, cactus, olives, and beetles all have in common?

Answer: They are sources of yeast in the Phaff Yeast Culture Collection!

The Phaff Yeast Culture Collection is one of the largest collections of wild yeast in the world. Academic and industrial resarchers utilize this collection for a variety of research and applications, including pigments, enzymes, food ingredients, and hosts for protein expression.

The Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity went into effect in October 2014. The Phaff Yeast Culture Collection contains many microbes of international origin. All reasonable efforts are made to conform to expectations of the Nagoya Protocol. Please contact the Curator for more information.
