Astrobiology experiment to study how microorganisms behave in the space environment; specifically to monitor bacterial communication.


The UVigo SpaceLab team is currently developing a CubeSat mission called BIXO (Bacteriological Intercommunication eXperiment in Orbit) to study the impact of prolonged exposure to radiation and microgravity in the space environment on the cell-to-cell communication process of Chromobacterium violaceum. The mission involves conducting three rounds of experiments on this bacteria over nine months, which requires the preservation of the bacteria in a dormant state for long periods. Therefore, successful preservation is a critical requirement for the mission's success.

Introduces the freeze-drying method as a powerful alternative for preserving C. violaceum cells and maintaining their viability for the mission. Additionally, it will detail the entire experimental process for obtaining the lyophilized samples of the bacteria, including the integration of the lyophiles into the satellite and an assessment of their viability.
