Scientists have successfully created sourdough bread using yeast found in the 5,300-year-old remains of Otzi the Iceman, whose mummified body was discovered in the Ötztal Alps in 1991. The research team, led by microbiologist Mohamed Sarhan at the Eurac Research Institute for Mummy Studies in Italy, found that the cold-adapted yeasts had infiltrated Otzi's corpse shortly after his death and had survived in cold environments for millennia. Sarhan stated that the resulting dough was 'very very good,' suggesting that these ancient yeasts could be cultivated for future use in bread and beer production. Otzi, believed to have died from an arrow wound in his 40s, was Europe's oldest known natural mummy and has been the subject of extensive research. His gut microbes resemble those found in modern non-Westernized populations, indicating a unique microbiome. The presence of modern microbes from conservation efforts raises questions about their impact on the preservation of Otzi's remains, prompting further investigation.
