Researchers extract cold-loving yeast strains from the mummified remains of Ötzi the Iceman, a prehistoric man preserved in Alpine ice and discovered in 1991 on the Italy–Austria border. Multiple outlets report that the yeast is recovered from or associated with Ötzi’s body and that scientists then use these ancient yeast strains to bake a sourdough loaf. The work is described as taking months and as drawing on earlier microbiome-focused research into microorganisms preserved on and inside the frozen remains. Although reports emphasize the unusual origin of the yeast, they agree on the core finding: viable yeast compatible with bread-making is found in the preserved mummy and can successfully produce sourdough. Several sources also note that the researchers look beyond bread. In particular, they plan follow-up experiments to test whether yeast strains recovered from Ötzi could be used to brew beer as well. The publications consistently frame the results as an intersection of microbiology and food science, using an ancient preservation environment to obtain microbial strains for fermentation.
