A team of researchers has made a groundbreaking discovery in the field of microbiology, finding that the frozen remains of Ötzi, a 5,300-year-old mummified man, harbour metabolically active microbes.
The research, conducted by a team of scientists from the University of Innsbruck, Austria, and the University of Trento, Italy, reveals that Ötzi's body still contains a diverse range of microorganisms, including bacteria that were likely present when he was alive.
The team used advanced DNA sequencing techniques to analyse the microbial community in Ötzi's gut and found that it was dominated by bacteria from the genus Lachnospiraceae. These bacteria are known to play a key role in the breakdown of complex organic matter and the production of vitamins.
In addition to the bacteria, the researchers also discovered cold-tolerant fungi that had colonised Ötzi's body after death. These fungi are able to survive in extreme temperatures and may have played a role in breaking down Ötzi's body after he died.
The study, which was published in the peer-reviewed journal Nature, provides new insights into the microbial life that exists in extreme conditions. The findings could have significant implications for our understanding of microbial ecosystems and the development of new technologies for preserving and storing biological materials.
According to Dr. Verena Schuenemann, a co-author of the study, 'Our results show that Ötzi's body is not just a museum piece, but also a time capsule that contains a unique community of microorganisms that can provide insights into the past and the present.'
