Which is the closest relative of D radiodurans?

These genes contain subunits that are characteristic of archaea genes. Genetics coupled with the extreme lifestyles seen in these bacteria indicate that the members of phyla Thermus-Deinococcus are the closest living relatives of the archeabacteria. This is a phylogenic tree provided by Dr. Michael Daly.

Is Deinococcus radiodurans an extremophile?

The Guinness Book of World Records says that Deinococcus radiodurans is the world's most extremophile bacterium. As its name suggests, this bacterium can deal with radiation. It has even been found on the inside walls of nuclear reactors.

Is Deinococcus radiodurans eukaryotic?

D. radiodurans is a prokaryote and thus differs considerably from eukaryotes in gene composition, methods of protein expression, codon preference and so on. Moreover, PprI protein has no homologous analogue in mammalian cells.

Where are Deinococcus radiodurans found?

The bacterium seems to live everywhere and nowhere. It has been found in environments as diverse as elephant dung and granite in Antarctic dry valleys (the environment on Earth thought to most closely resemble Mars), but no one really knows what the microbe's natural habitat is.

How did Deinococcus radiodurans evolve?

radiodurans had a Martian origin. They suggested that evolution of the microorganism could have taken place on the Martian surface until it was delivered to Earth on a meteorite.

When was Deinococcus radiodurans?

Deinococcus radiodurans strain R1 was the first of the deinobacteria to be discovered and was isolated in Oregon in 1956 (7) from canned meat that had spoiled following exposure to X rays.

Is Deinococcus radiodurans a Thermophile?

Thermus thermophilus and Deinococcus radiodurans belong to a distinct bacterial clade but have remarkably different phenotypes. ... thermophilus is a thermophile, which is relatively sensitive to ionizing radiation and desiccation, whereas D. radiodurans is a mesophile, which is highly radiation- and desiccation-resistant.

What does Deinococcus radiodurans do to humans?

Dein-ococcus radiodurans, one of the most radioresistant organisms known, is extremely resistant not only to ionizing radiation but also to UV, desiccation, and oxidizing and electrophilic agents. Deinococcus radiodurans can withstand acute doses of ionizing radiation on the order of 10kGy (2).

Is Deinococcus radiodurans aerobic?

Deinococcus radiodurans is an exceptionally radiation-resistant microorganism capable of surviving acute exposures to ionizing radiation doses of 15,000 Gy and previously described as having a strictly aerobic respiratory metabolism.

What shape is Deinococcus radiodurans?

Our knowledge of bacterial nucleoids originates mostly from studies of rod- or crescent-shaped bacteria. Here we reveal that Deinococcus radiodurans, a relatively large spherical bacterium with a multipartite genome, constitutes a valuable system for the study of the nucleoid in cocci.

What does Deinococcus radiodurans eat?

This chemoorganotroph thrives in an aerobic environment with the ability to utilize a vast array sugars, amino and organic acids as a carbon source for catabolism. It basically eats like a 16 year old high school football player, anything and everything it can!

Can Deinococcus radiodurans be killed?

A small number of unrelated prokaryotic and eukaryotic radiation-resistant species, such as the bacterium Deinococcus radiodurans, are unusually resistant to killing following exposure to ionizing radiation and other noxious conditions and environments such as desiccation (1).

Can Deinococcus radiodurans survive in space?

The extraordinarily resistant bacterium Deinococcus radiodurans withstands harsh environmental conditions present in outer space. Deinococcus radiodurans was exposed for 1 year outside the International Space Station within Tanpopo orbital mission to investigate microbial survival and space travel.

How is Deinococcus radiodurans used in bioremediation?

Deinococcus radiodurans is known as the world's toughest bacteria and it is the most radiation resistant organism known. ... Deinococcus has been genetically engineered for use in bioremediation to consume and digest solvents and heavy metals, even in a highly radioactive site.
