Meet a microbe: Deinococcus radiodurans

Meet Deinococcus radiodurans, one of the world’s toughest bacterium. It’s an extremophile and one of the most radiation-resistant organisms known on Earth. This hardy little bacterium can survive over a thousand times the amount of radiation that would kill a human. Its tolerance to many harsh conditions has earned itself the name “Conan the Bacterium,” after the movie Conan the Barbarian. D. radiodurans is a spherical bacterium and four individual cells are typically stuck together forming a square shaped cluster. Aside from radiation resistance, D. radiodurans is also resistant to ultraviolet light and desiccation. (more…)
