After 7,000 years without light and oxygen in Baltic Sea mud, researchers bring prehistoric algae back to life

Summary

Nutrition label

90% Informative

A research team led by the Leibniz Institute for Baltic Sea Research Warnemünde was able to revive dormant stages of algae that sank to the bottom of the Baltic Sea almost 7,000 years ago .

Despite thousands of years of inactivity in the sediment without light and oxygen, the investigated diatom species regained full viability.

Researchers also analyzed the genetic profiles of the resurrected algae using microsatellite analysis .

At around 7000 years old , the cells of this diatom are among the oldest organisms to have been successfully revived from an intact dormant stage.

The revived algae strains will therefore be further tested under different conditions in the future.

Further genetic analyses of the reactivated algae strains are expected to contribute to a better understanding of the causes of these genetic changes.
