Research Paper On Deinococcus Radiodurans

Deinococcus radiodurans (D. radiodurans) was discovered in 1956 by Arthur W. Anderson at the Oregon Agricultural Experiment Station in Corvallis, Oregon. There was an experiment to determine if processed foods can be sanitized by using great amount of gamma radiation. A can of meat was revealed that radiation, which was believed to destroy all known types of lifestyle, has been damaged and D. radiodurans was separated.
D. radiodurans is known for its radiation-resistant qualities. Being that it is mesophilic, this variety develops relatively well between 30-37 ° C. Deinococcus radiodurans has an original quality that can recover both single- and double-stranded DNA.
What makes D. radiodurans so special? It is the ability of the harmful bacteria …show more content…
The harmful bacteria is easily grown and seem to cause no disease. This bacterium is reddish, nonmotile, and gram positive with a unique cell wall. The wall contains multiple layers and an outer membrane. The genome includes two round chromosomes, one 2,650,000 platform sets, and the staying 412,000 platform sets, as well as a megaplasmid of 177,000 platform sets, and a plasmid of 46,000 platform sets. It has about 3195 genetics. In the set stage, each bacterial cell contains four duplicates of this genome; when rapidly growing each harmful bacterium contains 8-10 duplicates of the genome. The bacterium used to be called micrococcus radidurans on the basis of its morphological and physiological characteristics. The 16S rRNA analysis indicated that it was in a new family “Deinococcacae” which renamed to Deinococcus radiodurans. The bacterium has been studied for medicinal purposes, toxic waste cleanup, and in the search for exterestrial life. Also, the major application for D. radiodurans is waste cleanup due to its ability to withstand radiation. Deinococcus radiodurans could survive life on Mars due to its radiation and cold. Deinococcus radiodurans is an extremophilic harmful bacteria
