Scientists Revive Living Microbes From Ötzi the Iceman

Overview

• A peer‑reviewed study by Eurac Research published in Microbiome reported Wednesday that researchers cultured viable microbes from Ötzi, including cold‑adapted yeasts and Staphylococcus species.
• Scientists used targeted samples from skin, organs, meltwater, external ice, discovery‑site soil and the museum environment to separate ancient gut taxa, glacial fungi and modern contaminants.
• Laboratory culture experiments showed several cold‑tolerant yeasts (for example Glaciozyma watsonii and Mrakia robertii) and some bacteria multiplied after thawing, proving long‑term viability.
• The team found that routine museum procedures, such as spraying distilled water, introduced contemporary microbes to the mummy’s surface and museum staff say they are increasing microbiological monitoring.
• Beyond conservation, researchers note the isolates could have practical uses in medicine and industrial fermentation and the work sheds new light on prehistoric human gut microbes and diet.
