What to know about Ötzi the Iceman and his microbiome—a 5,300-year-old relationship

Researchers at Eurac Research have analyzed the microbiome of Ötzi the Iceman, distinguishing between original gut flora and cold-adapted yeasts acquired from the glacial environment. The study suggests these microorganisms are dynamic and may have potential applications in industrial low-temperature fermentation.

Why it matters

The study provides insights into a complex microbiome, ranging from the gut flora of a Copper Age human to cold-adapted yeasts.

Common ground

Using a variety of samples and methods, the researchers were able to differentiate which microorganisms were already present in the body during his lifetime and which only colonized it after his death—both during the time in the glacier and over three decades…
