[1] It is able to form thick biofilms on non-living surfaces, such as printing machines, glass, stainless steel, polystyrenes, polyethylene, etc., which are characterized by adhesion threads and lack of a slime matrix.

Attachment is assisted by extracellular polymeric substances (EPS) with adhesion being mixed on the surface of the cell, rather than uniformly spread.

It is proposed that in this lack, D. geothermalis prefers to utilize any available carbon for metabolism that reduces oxidative stress or reactive oxygen species (ROS).

Additionally, there are protein repair enzymes that the bacterium can use to combat oxidative stress, as well as up-regulating catalase and superoxide dismutase.

Due to the organism's reduction of radioactive materials and ability to withstand high temperatures, it has been proposed they be utilized in bioremediation efforts against toxic habitats.

[10] The two main experiments will test the resistance of a variety of extremophile microorganisms biofilms and planktonic cells, including Deinococcus geothermalis to long-term exposure to outer space and to a Mars simulated environment.

After 2 years, the mission was able to reveal that D. geothermalis biofilms and planktonic cells survived desiccation, UV radiation, and harsh Mars-like conditions.
