Abstract
The stratospheric microbiome has been investigated several times using the methods of classical microbiology. In this experiment, we have combined them with some novel approaches including whole- metagenome amplification, Maldi TOF mass spectrometry and Sanger DNA sequencing. The results of the experiment may provide the scientists with knowledge about the mechanisms of survivability of microorganisms in stratospheric conditions such as high doses of UV and cosmic radiation, low temperature and low humidity. The preliminary results have shown that the stratosphere is very poor in microorganisms in comparison to the regular, tropospheric air. Also the investigation is very difficult due to many problems with both small amounts of biological material and the high risk of contamination. However, contamination is possible to control, and modern methods of biotechnology help in the research of low quantities of material. The experiment was launched from Esrange Space Center in September 2021, onboard BEXUS 30 balloon mission conducted within the REXUS/BEXUS programme.
