Certain bacteria and fungi show a remarkable ability to persist, and even thrive, in high-radiation environments. These include the bacterium Deinococcus radiodurans and the fungus genus Aspergillus. Some of these organisms form biopolymer pigments such as carotenoids and melanins, which are thought to have an important role in the radioresistance of the organisms. For this reason, we are conducting research in space environments to understand the impact of radiation on biological systems and the most effective adaptive strategies. In this work, we examine the growth and behavior of several species while exposed to radiation to determine mechanisms by which they may adapt to these harsh conductions.
Below: Six selected bacteria and fungi will be grown on petri dishes in the capsule and imaged over a 30-day period on the ISS in March 2020, during which time they will be exposed to extreme ionizing radiation.

“RadioFungi” was funded by the SEI-TRISH Grant (Space Exploration Initiative-Translational Research Institute for Space Health) in Summer 2019.
