How bacteria survive in the permafrost region of Antarctica



Scientists noticed that when exposed to extremely low temperatures, bacteria are reduced to the smallest possible size – 200 nanometers. At this point, they seem to “fall asleep” and stop eating.

To make sure of this in practice, scientists have improved the living conditions for bacteria – they increased the humidity and temperature to the highest possible level for Antarctica. The hypothesis was confirmed: the bacteria began to grow in size and consume nutrients. Their total number increased rather quickly.

In addition to theoretical conclusions, scientists see a practical component in the results of the experiment: by understanding the mechanism of adaptation of bacteria to extreme conditions, it is possible to improve the technologies for the production of drugs and the selection of frost-resistant agricultural plants.
