Scientists Make Sourdough Bread With Ancient Yeast From Ötzi the Iceman

Ötzi the Iceman mummy in the South Tyrol Museum of Archaeology.

In an astonishing blend of archaeology and baking, scientists have successfully cultivated ancient, cold-adapted yeast found on the body of Ötzi the Iceman to bake sourdough bread. This remarkable achievement not only offers a tantalizing taste of the past but also reveals that the famous 5,300-year-old mummy is a dynamic biological system, still hosting active microorganisms millennia after his death in the freezing Alps.

Ötzi, discovered by hikers in 1991 in the Ötztal Alps on the border of Austria and Italy, is perhaps the most intensely studied human mummy in history. Since his discovery, researchers have learned about his health, his tattoos, and his last meal of ibex, red deer, and einkorn wheat. Now, a recent study published in the journal Microbiome by researchers from the Eurac Research Institute for Mummy Studies in Italy has unveiled a complex microbial ecosystem living on and inside the Iceman.

By analyzing swabs from Ötzi’s skin, thawed water from his remains, and soil from the discovery site, the team distinguished between ancient microbes that colonized him shortly after his death and modern ones introduced during conservation. To their surprise, they discovered four strains of cold-loving yeasts, including Glaciozyma, which are typically found in extreme environments like Antarctica.
