Scientists find yeast in frozen mummy's guts, use it to make bread
Scientists have discovered yeast in the gut of Oetzi the Iceman, a frozen mummy over 5,300 years old. They successfully used this ancient yeast to create sourdough bread after extensive experimentation. The findings reveal that Oetzi's body hosts living microorganisms that provide insights into ancient human life and microbiomes.
- ▪The yeast discovered in Oetzi's gut can survive sub-zero temperatures and is believed to have entered his body shortly after death.
- ▪The research team successfully reproduced the gut yeast and created a sourdough loaf after three months of effort.
- ▪Analysis of Oetzi's microbiome revealed gut bacteria that are nearly absent in modern humans but found in some indigenous tribes.
