Scientists Discover Ancient Yeast in Mummy, Use It to Bake Sourdough Bread
Researchers have discovered yeast in the gut of Oetzi the Iceman, a 5,300-year-old mummy found in the Alps. This yeast, which thrives in cold conditions, was used to bake sourdough bread. The mummy, discovered in 1991, has been preserved at a constant temperature, allowing scientists to study its microbiome. The yeast, believed to have entered Oetzi's body post-mortem, was reproduced in a lab setting. The study, published in the journal Microbiome, highlights the presence of both ancient and modern microbial life in the mummy, offering insights into ancient human life and potential environmental applications.
