Deinococcus radiodurans
It may be possible to make other bacteria as radiation resistant as D. radiodurans by changing their genetics. One research team in China is trying to insert an expressive recombinant Mn-SOD protein from D. radiodurans into E.coli BL21. The real challenge here is making the protein self-sustaining in the new species. The team has "provided the foundations for further studies and applications of the recombinant Mn-SOD".
