How is it that some bacteria live in the hot springs of Yellowstone Park at temperature up as high as 73 C?
Extreme thermophiles have adapted unique ways to surviving harsh conditions. They're enzymes are specially designed to resist denaturing at high temperatures. What's really amazing is their DNA. Extremophile DNA is positively supercoiled (this describes the way it is twisted around itself) which makes it harder to separate the strands. DNA in most other species is negatively supercoiled (meaning it's wound up on itself in the opposite direction as positively supercoiled DNA). Since DNA is the building block of life, it makes sense that you need to be able to protect it from the environment. Extremophiles do just that by positively supercoiling it. It is much more resistant to heat denaturing than other DNA would be, which helps the bacteria to survive.
Some bacteria can live in high heat conditions, known as thermophiles. These bacteria have adapted to thrive in environments with temperatures ranging from 113°F to over 230°F. They are often found in places such as hot springs and deep-sea hydrothermal vents.
High temperatures will kill the bacteria in the food, although it wont kill all bacteria just enough that it is healthy to eat
When bacteria is subjected to high temperature, they will die just as you would.

What is the name of the process for killing bacteria with high heat?
Sterilizing I think. You kill any bacteria with heat or radiation.
What is An organism that can live in a very high temperature of water?
One example of an organism that can live in very high temperatures in water is the thermophilic bacteria Thermus aquaticus. These bacteria are commonly found in hot springs and hydrothermal vents where temperatures can reach over 70°C. This organism is known for its ability to thrive in extreme heat due to special adaptations in its enzymes.
What are heat resistant structures in bacteria?
Heat-resistant structures in bacteria include endospores, which are dormant, tough structures that can survive extreme conditions like high temperatures. Endospores are formed by some bacteria as a defense mechanism to protect their genetic material. They allow bacteria to withstand harsh environments and continue to exist in unfavorable conditions.
Are leptospira species resistant to heat?
Leptospira species are not resistant to heat and can be killed by high temperatures. Proper heat treatment, such as boiling water or steam sterilization, can effectively control and kill Leptospira bacteria.
Are Archeabacteria simple or complex celled?
Archeabacteria are the most simple celled organisms. they can thrive in hazardous regions because they are so simple. being simple allows them to live in such harsh regions like high salt concentrations, high heat and high pressured areas. they are the simplest form of prokaryotes (bacteria are also prokaryotes).
What is the name of the process for killing bacteria with high heat?
Sterilizing I think. You kill any bacteria with heat or radiation.
Why was the mixture of heat killed s bacteria and r bacteria virulent?
The live R bacteria acquired a capsule and became live, virulent S bacteria.
Does heat kill the live cultures in buttermilk?
Yes, excessive heat can kill the bacteria in buttermilk.
What is Fredderick Griffith hypothesis?
Frederick Griffith hypothesized that live, harmless bacteria and the heat-killed bacteria were mixed, some factor was transferred from the heat-killed cells into the live cells! it has nothing to do with bats flying thru walls!!
Why did heat kill Griffith's S bacteria?
Heat killed S bacteria in Griffith's experiment was because of the temperature of the heat. The heat was high enough to kill many things like proteins and enzymes, so the bacteria could not create endospores to harm the immune system.

These bacteria are commonly found in hot springs and hydrothermal vents where temperatures can reach over 70°C.

What happened when Griffith injected mice with a mixture of heat-killed pneumonia-causing bacteria and live bacteria of the harmless type?
that it was very gay
What does it mean that the us is idealogically homogeneous?
It means that their brains have been processed with high heat to keep out the bacteria.
Who Was responsible for the experiment with mice and bacteria that led to the hypothesis that when two bacteria were mixed together something was passed to the living cells?
This experiment was conducted by Frederick Griffith in 1928. He observed that when he mixed a harmless strain of bacteria with a heat-killed virulent strain, the harmless bacteria were transformed into a virulent form. This led to the hypothesis that something in the heat-killed bacteria had transformed the live bacteria.
Why are bacteria unable to live on earth?
Bacteria CAN live on Earth.
What are heat resistant structures in bacteria?
Heat-resistant structures in bacteria include endospores, which are dormant, tough structures that can survive extreme conditions like high temperatures. Endospores are formed by some bacteria as a defense mechanism to protect their genetic material. They allow bacteria to withstand harsh environments and continue to exist in unfavorable conditions.
Which domain do organisms live in extreme environments?
Organisms that live in extreme environments are often found in domains Archaea and Bacteria. These extremophiles thrive in conditions such as high temperatures, acidic environments, high salinity, or high pressure, where most other organisms cannot survive.
