Conan the Bacterium

Definition

Conan the Bacterium, scientifically known as Deinococcus radiodurans, is an extremophilic bacterium renowned for its extraordinary resistance to radiation and other environmental stresses. It is a model organism for studying DNA repair mechanisms and microbial survival in extreme conditions.

5 Must Know Facts For Your Next Test

1. Deinococcus radiodurans can withstand up to 5,000 Gray of ionizing radiation without losing viability.
2. It has an efficient DNA repair system that allows it to quickly mend damaged chromosomes.
3. This bacterium was first discovered in 1956 during experiments aimed at sterilizing canned food using high doses of gamma radiation.
4. Deinococcus radiodurans forms tetrads (groups of four cells) which may aid in its resilience against DNA damage.
5. Its unique ability to resist desiccation makes it a subject of interest for astrobiology and the study of life on Mars.
