A recent study has found viable cold-adapted yeasts in the remains of Ötzi the Iceman, suggesting that his microbiome may influence his preservation. Conducted by a team led by Albert Zink, the research highlights the dynamic nature of Ötzi's remains and the importance of understanding microbial contamination for conservation efforts.
- 01The study identified four ancient species of yeast that remained viable in Ötzi's remains, indicating they persisted during his preservation in ice.
- 02Researchers analyzed samples from Ötzi's body and the glacier where he was found, revealing genetic traces of gut microbes.
- 03The findings suggest Ötzi is a dynamic biological interface rather than a static relic, emphasizing the need for careful preservation to prevent decomposition.
- 04Ötzi's remains are kept at –6° Celsius to simulate glacial conditions, which is crucial for maintaining their integrity.
- 05The study underscores the importance of understanding microbial contamination for the future conservation of Ötzi's remains.

A new study published in the journal Microbiome has revealed that Ötzi the Iceman's remains contain viable cold-adapted yeasts, which may have colonized him during his time in a glacier. The research team, led by Albert Zink, found genetic traces of gut microbes alongside these yeasts, suggesting that Ötzi's microbiome could impact his preservation. The study involved thawing Ötzi's remains and analyzing samples from his body, skin, and the glacier where he was discovered. The presence of four ancient yeast species indicates that Ötzi is not merely a static artifact but a dynamic biological entity. This finding is significant for conservationists who maintain Ötzi's remains at –6° Celsius to prevent degradation. Experts emphasize that understanding the microbial environment surrounding Ötzi is crucial for ensuring the long-term preservation of this important archaeological find, which has provided insights into life during the Copper Age.
