But why is Halobacterium such a tenacious survivor?
She believes the answer stems from the fact that Halobacterium naturally lives in some rather inhospitable places: ultra-salty bodies of water such as the Dead Sea.
Evolving to cope with a salty lifestyle could explain why Halobacterium is so good at surviving radiation and other ravages, DiRuggiero reasons.
In some experiments, they exposed Halobacterium cells to beams of intense UV radiation.
coli that lives in the human gut, would have been completely exterminated, yet 80 percent of the Halobacterium cells survived.
In other experiments, the researchers used a vacuum chamber at NASA's Goddard Space Flight Center to expose cells of Halobacterium to a space- like vacuum (1 millitorr).
