Meanwhile, Deinococcus radiodurans is completely resistant to up to 5,000 Gy of gamma radiation, cultures routinely survive exposure to 15,000 Gy, and some strains have been reported to have survived 50,000 Gy of radiation [2,4]. Why not scuba dive with sharks? Deinococcus radiodurans was first isolated when it spoiled a can of meat that had been sterilized using gamma radiation. Thx again, Your email address will not be published. A well-protected functional proteome ensures cell recovery from extensive radiation damage to other cellular constituents by molecular repair and turnover processes, including an efficient repair of disintegrated … Endolithic cyanobacteria have also found a is deinococcus radiodurans harmful to humans January 15, 2019February 1, 2019- Animal Deinococcus Radiodurans: Bacterium very tough; it might survive on Mars Deinococcus radiodurans – it is a name present in the “Guinness Book of World Record” for being “the world’s toughest… Now, that you know that with such a complex name, there is a bacterium, you might be wondering how tough it is actually. It’s an extremophile and one of the most radiation-resistant organisms known on Earth. I¦ve been looking all over for this! Access to Scientific Mystery is through different social media: Deinococcus Radiodurans: Bacterium very tough; it might survive on Mars. The polyextremophile, gram-positive bacterium Deinococcus radiodurans can withstand harsh conditions of real and simulated outer space environment, e.g., UV and ionizing radiation. Deinococcus radiodurans was first discovered in 1956 in a can of ground meat that had been treated with large doses of radiation to remove all hazardous bacteria from the product. The fourth layer is the outer membrane, the fifth is a distinct electro-lucent zone, and the sixth layer consists of regularly packed hexagonal protein subunits. Meet Deinococcus radiodurans, one of the world’s toughest bacterium. When the studies on this bacterium are still pursuing, it is definitely in the minds of the scientists to use Deinococcus Radiodurans to search life on Mars or elsewhere, or help them understand how to avoid potential ‘cross-contamination’ between earthly and alien life forms. If someone became ill, treatment would start with drugs in from a small supply kept on hand, while the appropriate bugs were awakened to produce a regular supply. It is a resilient bacterium, in that it is resistant to radiation, UV light, hydrogen peroxide, and many other DNA Scientific Mystery presents information from the world of science fiction and the famous mysteries. Deinococcus radiodurans – it is a name present in the “Guinness Book of World Record” for being “the world’s toughest bacterium”. People who walk on all fours are rare but they do exist! Deinococcus radiodurans, or D. radiodurans, is a bacterium which is thought to be the most resilient in the world. Controversial films which years after release are still banned in few places. Golden Poison Frog: It’s among the most poisonous animals on planet, Blue Ringed Octopus: The most venomous marine animal, Pufferfish: Its poison is toxic than cyanide and still humans consume it, Inland Taipan: All details about ‘the most venomous snake in world’. Deinococcus radiodurans is one of my favorite species of bacteria (it even made the Guinness Book of World Records!). The bacterium Deinococcus radiodurans is a champion of extreme radiation resistance that is accounted for by a highly efficient protection against proteome, but not genome, damage. We use cookies to ensure that we give you the best experience on our website. Brazilian Wandering Spider can be deadly to humans; beware it! It can do it with absolute fidelity; the new genome looks as good as the old one. Deinococcus radiodurans Description and significance Deinococcus radiodurans is a red-pigmented, non-motile, spherical bacterium that is 1-2 µm in size. Deinococcus radiodurans can withstand 10,000 times the amount of radiation that would kill a human, earning it monikers like "Super Bug" and "Conan the Bacterium." The extremophilic bacterium Deinococcus radiodurans is well known for The scientists chilled the bacterium to -79C (the average temperature at Mars’ mid-latitudes). In addition, a ground-based simulation experiment with conditions, mirroring those from low Earth orbit, was performed. Save my name, email, and website in this browser for the next time I comment. Characteristics of Animals, those you already know, but not really know. So, clearly, it’s doing something differently.” Funding Agency Interest About a dozen laboratories around the world now study D. radiodurans. —Preceding unsigned comment added by 172.192.149.119 22:37, 24 March 2008 (UTC) No, there aren't any known pathogenic extremophiles. Scientisis have discovered that Deinococcus radiodurans can metabolize harmfu l toxic substances.We can utilize this special bacteria to break down toxic waste and other substances that are harmful to other organisms. Deinococcus radiodurans, the most radiation-resistance organism ever known and endure 1,500 Kilorad/hr gamma or UV radiation and grow in radioactive environment. Deinococcus radiodurans is listed in the Guinness Book of World Records as \"the world's toughest bacterium.\" And for good reason: The microbe can survive drought conditions, lack of nutrients, and, most important, a thousand times more radiation than a person can. Deinococcus radiodurans Deinococcus radiodurans has encountered severe scrutiny of its abilities from scientific research. People who walk on all fours are rare but they do exist! I came across it a few years ago when researching life that Now, that you know that with such a complex name, there is a bacterium, you might be wondering how tough it is actually. The name, ‘Deinococcus radiodurans,’ has been derived from the Greek language which literally translates to ‘strange-berry.’ It is a Gram-positive, nonpathogenic bacterium with an average cell diameter of 1 μm. Because of the manganese ions found in the cells, this … Not only has D.radiodurans been genetically modified for bioremediation applications, but also it has been discovered that it could perform a major role in biomedical research and in nanotechnology. The second layer is perforated, while the third layer is divided into numerous fine compartments. Richmond, Sridhar, and Daly suggest that D. radiodurans can be genetically manipulated to produce various drugs that humans might need while exploring Mars, then put on ice during the mission. Deinococcus radiodurans: A bacterium that can survives extremely high levels of radiation and therefore has high potential for radioactive waste cleanup. It is capable of withstanding acute irradiation doses of 1 500 kilorads, a level hundreds of times higher than most other organisms. The additional genomes might be the reason for the bacterium to recover at least one complete copy of its genome after exposure to radiation. From her research, we may be able to understand how to protect or repair cells from the harmful effects of radiation. There is a high enough level of radiation that can kill the bacteria. The innermost layer is the plasma membrane. Required fields are marked *. Well, the microbe is almost indestructible, bearing the capability of surviving at the surface of Mars which is bombarded with intense radiation.  It can also survive the drought conditions and lack of nutrients. 10 haploid genome copies during exponential growth and 4 genome copies during exponential growth and 4 genome copies during phase!, and website in this browser for the bacterium to -79C ( genetic...
