Scientists have successfully baked sourdough bread using yeast extracted from the 5,300-year-old mummified body of Ötzi the Iceman. Researchers from Eurac Research obtained a detailed picture of the microbes living on Ötzi's remains, discovering both ancient gut bacteria and cold-loving yeasts. According to lead author Mohamed Sarhan, 'We made some really good dough with it.' The experiment involved cultivating the yeast in a refrigerator to adapt it to the flour environment before achieving a fully risen dough within 24 hours.
Key Takeaways
Scientists have successfully used yeast collected from Ötzi the Iceman's 5,300-year-old mummy to bake sourdough bread. Researchers discovered thriving communities of microbes on Ötzi’s remains, including cold-loving yeasts that were used to create a functioning sourdough starter. The study provides insights into ancient microbial life and its potential applications in modern food production.

The discovery of these microbes provides valuable insights into early human history and microbial life. Ötzi's mummified remains, uncovered in 1991 on the border between Austria and Italy, have been preserved at -6°C (21°F) at the South Tyrol Museum of Archaeology. The researchers identified three distinct microbial worlds: ancient gut bacteria from Ötzi's lifetime, cold-adapted microorganisms from the glacier environment where his body lay, and modern microbes introduced during museum conservation.
The study reveals that Ötzi is not a static relic but a dynamic ecosystem hosting living organisms. The cold-adapted yeasts found on Ötzi’s skin and internal body water are particularly remarkable for their ability to grow in such low temperatures. These findings raise questions about the long-term integrity of the mummy and offer potential applications in food production, including bread-making and beer brewing.
The researchers plan to involve specialized teams from the food sector to further explore these possibilities. The study also highlights the disappearance of certain gut bacteria from modern Western diets due to dietary shifts, antibiotic use, and reduced exposure to natural environments. Ötzi's microbiome offers a rare window into the intestinal ecosystem of a Copper Age human.
Beyond bread-making, the researchers are considering other applications for these ancient yeasts. Mr Sarhan mentioned discussions with experts from Weihenstephan about potentially making beer using Ötzi’s yeasts. The study underscores the ongoing significance of Ötzi's remains in providing insights into early human history and microbial life.
