Bacteria, Iron Cooperate to Clean Uranium from Water Since 2009, SLAC scientist John Bargar has led a team using synchrotron-based X-ray techniques to study bacteria that help clean uranium from groundwater in a process called bioremediation. . . . The bacteria make their own, even tinier allies - nanoparticles of a common mineral called iron sulfide. Then, working together, the bacteria and the iron sulfide grab molecules of a highly soluble form of uranium known as U(VI), or hexavalent uranium, and transform them into U(IV), a less-soluble form that's much less likely to spread through the water table.

Bioremediation of uranium-contaminated groundwater: a systems approach to subsurface biogeochemistry.

Abstract
Adding organic electron donors to stimulate microbial reduction of highly soluble U(VI) to less soluble U(IV) is a promising strategy for immobilizing uranium in contaminated subsurface environments. Studies suggest that diagnosing the in situ physiological status of the subsurface community during uranium bioremediation with environmental transcriptomic and proteomic techniques can identify factors potentially limiting U(VI) reduction activity. Models which couple genome-scale in silico representations of the metabolism of key microbial populations with geochemical and hydrological models may be able to predict the outcome of bioremediation strategies and aid in the development of new approaches. Concerns remain about the long-term stability of sequestered U(IV) minerals and the release of co-contaminants associated with Fe(III) oxides, which might be overcome through targeted delivery of electrons to select microorganisms using in situ electrodes.

mycelium concentrate radioactive waste "It has been found that various species of mushrooms can thrive and breakdown radioactive waste such as that found in Japan currently. Gomphidius glutinosus can break down radioactive cesium. In terms of volume of soil remediated the mushroom mycelium concentrate the radioactive substance and it is placed in the fruiting body of the basidiocarp. The radioactive waste is still in it's energetic form, just concentrated somewhere else. If there is a need to gather the radioactive waste it is just a matter of gathering the fruiting bodies of the mushrooms. In this manner Oyseter mushrooms can clean up oil spills in the soil quite easily." - Stamets, Paul. Mycelium Running. Berkeley: Ten Speed Press, 2005.

The Hindu Michigan State University have unravelled the mystery of how microbes generate electricity while cleaning up nuclear waste and other toxic metals. Details of the process, which can be improved and patented, are published in the current issue of the Proceedings of the National Academy of Sciences. cbsnews.com Gaetan Borgonie, a nematode specialist from Belgium, discovered radiation eating microbes in the rock walls of a South African mine.

The Scientist The bacterium Geobacter sulfurreducens lives by reducing metals, such as radioactive uranium, rendering them much less soluble and thus less of a threat to the environment. New research published yesterday (September 5) in the Proceedings of the National Academy of Sciences points to how they do it.

Possible breakthrough in Japan [click the link to watch video] Scientists in Japan think they may have found a way to remove caesium radiation from contaminated ground around the Fukushima nuclear plant damaged in the earthquake in March. It involves using microbes to attracts particles from the metal caesium in soil and water. So far results have been very encouraging and the scientists are keen to test the procedure on the ground as soon as possible.

Cladosporium sphaerospermum - fungi that thrives on radiation. "Researchers from the Albert Einstein College of Medicine in New York City, believe that the black fungus converts ionising radiation into usable energy, just as green plants convert sunlight. It appears that C. sphaerospermum copes with the DNA-damaging effects of radiation by having multiple copies of the same chromosome in every cell. This fungus is happy living even in the heart of the Chernobyl reactor, where it was discovered in 1999."

sunflowers remediate radioactive waste as noted above, the sunflowers will absorb the radioactive waste, then will have to be disposed of as contaminated trash. But what better way to get the radioactive waste out of the environment?

The Solution That Might Save Japan and the World From Radiation These microbes are called extremophiles and they have been known about since 1956. They can withstand radiation 15 times what would kill humans and they actually seek out and eat uranium and plutonium transforming them into far less dangerous substances.

Algae may help clean up nuclear waste Scientists at Northwestern University and Argonne National Laboratory have studied the way that bright green algae Closterium moniliferum found in fresh water ponds, soak up strontium and sequesters it. By using synchrotron X-ray microscopy available at the Advanced Photon Source at Argonne National Laboratory, the researchers were able to map out how green algae absorbs the strontium as well as study how other minerals like barium and calcium affect the process.

National Science Foundation: scientists discover bacteria that eat the by-products of radioactivity.

Bioremediation of Radioactive Waste One technology that holds promise for eventually reducing the toxicity and amount of radioactive waste is bioremediation, using live bacteria. This technology makes use of the ability of live cells or enzymes to clean and reduce the volume of waste.

Editor's Note: we have added this category to respond to the ongoing nuclear crisis in Japan. Our lesson from this is that strains of microbes "eat" nuclear waste, the same way nature eventually dispenses with nuclear waste. Therefore, we now have a Google Alert for the keywords "nuclear bioremediation," and will bring you developments in this field.

We urge officials in Japan to use natural means to enhance the bioremediation process. The future of friendly bacteria is bright. Find them, breed them, love them - and they will love you back. Start with green microorganisms, such as chlorella, spirulina, cilantro, and medicinal mushrooms.

Everyone else: pray that our prayers will help the natural process of nature take place, including a change of thinking in the human race. If we change our story about nature, we will treat it differently. Instead of regarding our planet as a thing to exploit for money, we could see it as a sacred debt. Humankind has taken a toll on the earth, especially in the last hundred years, and it is up to us to reverse that trend and remediate the damage.

Antarctic microbe discoveries Nature News, April 4, 2011, reports:
"Another strange discovery is a previously unknown Deinococcus—a group of bacteria known as the world's toughest—capable of tolerating γ-ray exposures 5,000 times greater than those survived by any other known organism, despite living 15 metres beneath the permafrost. These levels of radiation have never existed on Earth, so the source of the bacterium's resistance is a mystery. Theories put forth so far include that the microbe had an extraterrestrial origin. Blamey says that at this point, no theory has been discarded."
