Insights Into The Synthesis, Engineering, And Functions Of Microbial Pigments In Deinococcus Bacteria
The ability of Deinococcus bacteria to survive in harsh environments, such as high radiation, extreme temperature, and dryness, is mainly attributed to the generation of unique pigments, especially carotenoids.

DNA Damage And Survival Time Course Of Deinococcal Cell Pellets During 3 Years Of Exposure To Outer Space
The hypothesis called “panspermia” proposes an interplanetary transfer of life. Experiments have exposed extremophilic organisms to outer space to test microbe survivability and the panspermia hypothesis. Microbes inside shielding material […]
