(NewsNation) — Yeast found in the stomach of a 5,300-year-old mummy has been used by scientists to create sourdough bread.
Scientists from the Italian Eurac mummy research institute in Bolzano have announced that they have succeeded in baking a loaf of bread from yeast found in the stomach of Ötzi the Iceman.
Ötzi died a violent death approximately 5,300 years ago in the Alpine region on the modern border between Italy and Austria. An arrowhead was found in his left shoulder, causing fatal bleeding during an attack in the mountains.
After being discovered by tourists in 1991, his body was found and kept in the same sub-zero temperatures that kept it safe at the South Tyrolean Archaeological Museum in Italy.

Scientists have conducted the most comprehensive analysis to date of the microbial landscape of Ötzi the Hun, studying in detail the bacteria, fungi, and yeast in various tissues over more than three decades of research. Ötzi's body was preserved thanks to millennia of exposure to glacial conditions.
Researchers have identified three distinct microbial worlds within and on Ötzi's body. These include ancient gut bacteria that were part of his microbiome during life, cold-adapted microorganisms originating from the glacial environment in which his body was preserved, and modern microbes that emerged during three decades of museum conservation.
In an interview with AFP, lead author Mohamed Sarhan said they had succeeded in reproducing intestinal yeast and baking sourdough bread, which took three months to produce "very, very good sourdough bread.".
As for other uses for yeast, Sarhan said beer is "on the list.".
