Scientists Use Yeast from Oetzi the Iceman to Create Sourdough Bread
Researchers have discovered yeast in the gut of Oetzi the Iceman, a 5,300-year-old mummy found in the Alps, and have successfully used it to make sourdough bread. Oetzi, who was killed by an arrow and preserved in ice, was discovered in 1991. The yeast, found in his gut, skin, and water melted from his body, is capable of surviving sub-zero temperatures. This yeast, along with other microbes, provides a unique insight into ancient human life and the microbiome. The study, published in the journal Microbiome, highlights the presence of both ancient and modern microbial life in Oetzi's body, suggesting that these organisms have adapted to the cold environment over millennia.
