Do most of bacteria die in a temperature of 100C?

Answer 1

the answer to that is yes and also no. The reason is because it it depend on the type of bacteria you are talkilng about. There are some bacteria will die under the temperature of 100C, and there are die at 100C, and there are some that able to live above 100C but may die at 121C.

if the bacteria contain endospore/spore, then it is hard to kill them. people may use an autoclave to kill spore bacteria and the temperature to kill them is 121C in an autoclave.

overall, it is depend on what type of bacteria you are talking about.

p.s.: After I read the solution that other members post and answer your questions, most of the solutions are very good. But I don't know why they have a thumb down?

Answer 2

Yes. It the heat is really just there to denature enzymes as well as other things but simply boiling the water does not kill it as water boils at various temperatures around the world for example at around 0-1 miles above sea level water boils at around 100C but elsewhere say, upon a very high mountain it could boil at around 20C due to the great change in pressure.
Bacteria can also be kiled by extreem cold but can also be preserved. It all depends on how they are frozen. If Ice crystals are formed then the bacteria is usually destroyed as the cells become punctured and when 'defrosted' they lose everything withing them. But if no ice crystals are formed then when 'defrosed' the bacteria should not die.

Answer 3

100C for how long is the question...

Most as someone mentioned already, die at much lower temperatures. But some, such as Bacillus cereus, form highly resistant spores which may survive half an hour of boiling. Therefore, when conditions for growth become optimal again, the spores germinate, regenerating the bacteria again; effectively, they survive.

Also, some other bacteria, known as extremophiles or, in the case of high temperatures, thermophiles can survive such high temperatures quite well. One such organism named Thermophilus aquaticus survives at thermal vents on the ocean floor, where temperatures may be as high as 133 degrees celsius.

Answer 4

Yes, most bacteria do die at 100C. That is because not only internal water reaches the boiling point (as mentioned earlier), but also proteins are denatured. Many proteins are actually denatured at a lower temperature (as also mentioned). All enzymes (that bacteria, as well as almost all other living organisms need) are proteins, so, if critical enzymes are denatured, the cell (whether bacteria or our own) cannot do anything. However, as mentioned earlier, not ALL bacteria are killed at 100C.

That is why, in the laboratory (or at your dentist's office) they have autoclaves that are actually run at 121C to try to kill all bacteria. "TRY" because even at 121C, prions (the "mad-cow" agent) are NOT killed.

Answer 5

MOST die at that temperature
except of course the ones that live in hot springs and deep thermal vents, thats what they are adapted to..if you take them out of that temperature they'll die
where do you think we get TAQ polymerase from to do pCR so fast and efficiently? from a bacteria that can withstand that kind of temperature...before we found bacteria in those places we had to use a different polymerase for each round in the pcr because the enzyme would denature at the temperatures that were used, but now the TAQ can withstand the high temps because its situated for it

Answer 6

Alot bacteria will die when in contact with temperatures of 100 degrees celcius (the boiling point of water) but there are also some that wouldnt. Some bacteria live in hot springs deep in the ocean and can survive temperatures up to hundreds of decrees celcius. Also, there are bacteria in come typer of food that will not die when in contact with heat of 100 degrees celcius. Certainly, viruses need much more than 100 degrees to kill them.

Answer 7

yes most bacteria die at temperature of 100C, and this is the reason why people in 3rd world country boil their water before they dring it.

Answer 8

yes, this is why we are told to drink boiled water if we get upset stomachs and also for babies....

however some bacteria can survive at 100c

Answer 9

there are some bacteria that live by thermo-vents in teh deep atlantic rift, massive 300+ celcius and highly sulphorous (very acid) conditions - but most will denature around 100C

Answer 10

I somewhat have had ich many circumstances in my tanks and between the neatest issues to do is flow to your community fish shop and get some ich formula. those products works super. Boiling the water won't help. A water substitute will help in the adventure that your tank is in % of cleansing. The Oscar is bullying the Mollie because of the fact he needs to mark his territory. regrettably oscars whilst they are super sufficient will devour fish like mollies and goldfish or fish around that length for a classic meal, considering is their organic weight-alleviation plan. i could propose shifting between the fish out of the tank because of the fact the oscar will kill the mollie whether he can no longer in fantastic condition him into his mouth. wish this helps.
