What is radioresistant habitat?

Radioresistance is the property of organisms which are capable of living in environments with very high levels of ionizing radiation. ... A Brazilian study in a hill in the state of Minas Gerais which has high natural radiation levels from uranium deposits, has also shown many radioresistant insects, worms and plants.

Where can Deinococcus radiodurans be 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.

What are radioresistant organisms?

Extremophiles are organisms able to thrive in extreme environmental conditions. Microorganisms with the ability to survive high doses of radiation are known as radioresistant or radiation-resistant extremophiles.

What conditions can Deinococcus radiodurans survive in?

Deinococcus radiodurans is an extremophilic bacterium and one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile. It has been listed as the world's toughest known bacterium in The Guinness Book Of World Records.

Where are Barophiles found?

A piezophile, also called a barophile, is an organism which thrives at high pressures, such as deep sea bacteria or archaea. They are generally found on ocean floors, where pressure often exceeds 380 atm (38 MPa). Some have been found at the bottom of the Pacific Ocean where the maximum pressure is roughly 117 MPa.

What are radioresistant cells?

Radioresistance is a process in which the tumor cells or tissues adapt to the radiotherapy-induced changes and develop resistance to the IR. This is a complex process involving multiple genes, factors, and mechanisms [34, 35].

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!

How long do Deinococcus radiodurans live?

Now, new findings published today in Frontiers in Microbiology, based on that experiment on the International Space Station, show that the bacteria Deinococcus radiodurans can survive at least three years in space.

What does Deinococcus radiodurans do to humans?

Deinococcus radiodurans can withstand radiation levels 1000 times higher than would completely debilitate any human on earth. These amazing characteristics can be contributed to one main characteristic of Deinococcus radiodurans; its ability to repair damaged chromosomes.

How do radioresistant organisms survive?

DNA Repair

Some radioresistant extremophiles have developed a way to survive high levels of radiation. As it would in a normal cell, the radiation does actually break the microbe's DNA into pieces and mess it up. ... This process is how Deinococcus radiodurans, the second most radioresistant organism known, survives.

What is a radioresistant tumor?

Tumor Radioresistance

Clinically, a tumor is considered radioresistant when irradiation is unable to reduce its volume or when a recurrence occurs after a possible regression. However, tumors with histological characteristics identical to a radioresistant tumor can be highly responsive to radiotherapy treatment.

Can bacteria survive a nuclear explosion?

This bacteria can withstand 1,000x as much radiation as would kill a human. The bacteria is so resilient that it's been found on the walls of nuclear reactors. It's unique properties have fascinated scientists, who have proposed all kinds of applications for the bacteria that range from the practical to the whimsical.

Can Deinococcus radiodurans survive without water?

Toughest bacterium

The bacteria Deinococcus radiodurans can live in extreme sircumstances. The most extreme extremophile that is known at the moment is the Deinococcus radiodurans. This microbe can survive extreme cold, drought, thin air and acid.

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.
