Talk:Deinococcus radiodurans

message: Where's the evidence that it is resistant to heat? I've read that it is resistant to cold but not to heat.
:I see no evidence that it is, nor is there anything in reference no. 6 that indicates this.  The sentence by the below poster is not found in that article.  We use heat to kill it.  Other species of Deinococcus *are* thermophilic but not this one.  —Preceding unsigned comment added by 130.39.115.49 (talk) 22:12, 27 February 2008 (UTC)

text: I think that you meant the PMID in reference no. 6, which I have just fixed. The organism is resistant to all forms of stress, including dessication and heat. Reference no. 1 has information on this. I had to fix the PMID for that reference as well. --Ben Best 00:23, 15 October 2006 (UTC)

message: Should there be any mention about potentially Martian origins?  There's a BBC article about that here: http://news.bbc.co.uk/2/hi/science/nature/6191197.stm
: Maybe, but it's uncertain. I do agree that most likely panspermia happened between Earth, Mars, and some other planet/moon.137.118.105.152 (talk) 20:54, 20 February 2019 (UTC)

message: I have removed the statement:
" Certain scientists are trying to implement genes into D. radiodurans that will cause its protein to disable metals with which they come into contact. In doing so, this bacterium may be able to metabolize heavy metals such as plutonium, uranium, and other radioactive metals into harmless matter. "
This cannot be correct. Radioactive materials do not lose their radioactivity through chemical processes.
:Actually what happens is the radioactive metal is reduced or is caused to form a compound.  The resulting product, while still radioactive, becomes insoluble and easier to sequester.  So it's true that the metals are metabolized, but false that they become harmless.  Ask google about nuclear bioremediation for some links.Viracocha (talk) 22:18, 25 March 2008 (UTC)

message: In several locations within this article, the DNA repair capability of D. radiodurans is described as "unique". This is not the case. The process of repairing a DSB is common, what is unique however, is the accuracy (lack of errors) of the process in D. radiodurans compared to other prokaryotes, such as E. coli. See the below paper. The radioresistance of D. radiodurans is more likely attributable to the protection of its proteome by ROS scavenging. (which protects the DNA repair machinery, making it less error prone than in E. coli). --Appelflappenn (talk) 15:00, 29 April 2021 (UTC)

thread_title:  Info on bacterium? 

message: D. radiodurans is capable of withstanding an instantaneous dose of up to 5,000 Gy with no loss of viability
Point of improvement: Does viability not mean that it can survive under constant irradiation? So shouldn't the unit be how much gray per time unit? (Also, viability does not get me a link to an article) 88.159.73.156 (talk) 22:42, 4 February 2009 (UTC)
thread_title:  Viability for amount of grays? Not for amount of gray per day? 

message: :Deinococcus has been genetically engineered for use in bioremediation to consume and digest solvents and heavy metals, even in a highly radioactive site.
Could a knowledgeable editor rephrase this so it doesn't sound like it's able to actually destroy heavy metal atoms?  Comet Tuttle (talk) 19:53, 26 October 2009 (UTC)

message: Deinococcus Radiodurans is a species of bacteria capable of repairing DNA and in the absence of this gene, the bacteria can still repair DNA damage, but will not grow.  Deinococcus radiodurans can withstand an acute ino radiation of 5,000 Gy. Lý Lượng Tử (talk) 06:32, 1 May 2021 (UTC)
