Earth has its fair share of environments that we think extreme , but even in some of the harshest habitats , organisms have found a style to get by . In the deepest ocean , where the pressure level is vivid and there is no light , there are still Pisces the Fishes swimming around . Inunderwater vent , where there is an acid carbon dioxide surroundings , football game - sized mussels have discover a way to originate .
Even radioactive site that are dangerous for humans are ' abode fresh home ' for certain microbe . And now , research worker have line up a remarkable species of bacteria that ' breathes ' U and fly high in abandoned uranium ore processing sites . The new observe strain , which belongs to a class calledbetaproteobacteria , was found in the soil at an old uranium ore mill in Rifle , Colorado . The pulverization was once used for atomic weapons production and the website is still radioactive to this twenty-four hour period .
As described inPLOS ONE , the bacteria somehow take a spare negatron from the uranium in a mental process call ' decrease . ' It is unknown whether the resulting atomic number 92 is in a state safe enough for human beings to interact with . However , if this is the guinea pig , then it could be a refreshing way of clearing up uranium - polluted sites expeditiously . Scientists are also unsure of the potential encroachment these organisms could have on the surround , so more research want to be done .
“ biological science is a way to lick this contamination job , particularly in situations like this where the radionuclides are highly dilute but still present at levels take for hazardous,”saidProfessor Lee KerkhofofRutgers University .
It ’s not certain how this type of uranium - feed bacteria develop to flourish off of radioactive elements . It ’s plausibly a physical process similar to the way that some bacteria developresistance to antibiotics . It just so happened that this picky species “ pick up a inherited constituent that ’s now appropriate it to detoxify uranium , to actually grow on uranium ” said Kerkhof .
This research is part of theU.S. Department of Energyprogram to see if microorganisms can nibble forth at radioactive uranium and make it inert . The department is hoping that this will make any contaminated groundwater and well water secure to imbibe again .
" After the fresh discovered bacteria interact with uranium compounds in urine , the atomic number 92 becomes immobile,“saidKerkhof . " It is no longer dissolved in the groundwater and , therefore , ca n’t foul boozing pee brought to the surface . "
Kerkhof ’s worry for contaminated imbibing H2O do n’t end with the United States . If this mintage can be harnessed to make radioactive zona safe for human , then there are a quite a little of place that could benefit from it .
" There is depleted uranium in a lot of armor - piercing munitions , " hesaid , " so lieu like the Middle East that are know war could be exposed to high tier of uranium in the groundwater . "
