It actually depends on the kind of bacteria. Based on their temperature requirements (temperatures at which they grow) bacteria are classified as psychrophiles (very low temperatures... even below zero).. mesophiles (above zero to say 20-30 on an average...).. thermophiles (above 50).. extreme thermophiles (very extreme temperatures such as hot springs.. may be in hundreds...).

Bacteria die when they are refrigerated or frozen?
No. That is a misconception. Most can remain very cold or even frozen and will begin to be active again when warmer.
Does bacteria die when in the freezer?
Yep. There are some uncommon bacteria (psycrophiles) that are able to grow at low temperature, as Arthrobacter.
What effect does low temperature have on bacteria?
every microbe require optimal temperature for its metabolic rates. when ever temperature increases metabolic rate of microbe decreases and dies.in low temperature microbes will be in inactive form.it doesn't die but stay in inactive form.
Which bacteria can grow in the refrigerator?
It depends entirely on the type of bacteria and the temperature in the fridge.
What happens to all bacteria in frozen food?
It depends on how quickly the food goes from room temp to frozen. If freezing occurs slowly, like when you put something into a normal household freezer, ice crystals are able to form in the cells and many (most) bacteria die. Some however, survive and are basically dormant (in microbiology the definition of "death" is that all cells are killed and cannot grow back). Refrigeration and freezing therefor are considered bacteriostatic, not bacteriocidal. When you remove the food item from the freezer it is not sterile, since some cells survive. Of course, you know this intuitively, because if you leave it out, it will "go bad". That is the bacteria recolonizing the tissues. If you are able to rapidly freeze cells (as is done in biology labs, with a ethanol slurry), water crystals do not have time to form. This is how cells are prepared to be stored in deep freeze and can be kept this way for long periods of time.
What happens to bacteria in frozen food?
The bacteria in frozen food die. This is because bacteria need food, water, and a warm temperature in order to survive.
Does the bacteria in frozen yogurt die?
No it doesn't to kill bacteria in frozen yogurt you would somehow disintegrate the bacteria which is impossible at this moment.
Bacteria die when they are refrigerated or frozen?
No. That is a misconception. Most can remain very cold or even frozen and will begin to be active again when warmer.
What kind of temperature destroys most bacteria?
73 degrees Cthat's the temperature were the bacteria die
Is it true that the more the temperature is lower the more the bacteria will die?
The bacteria will not die at lower temperature but will slow down or stop the formation of more bacterias, therefore you but food in the refrigerator.
Will freezing a germ kill it?
the answer is yes. this is because the decreasing temperature would cause most of the bacteria cells to die and eventually the bacteria would die.

Does the temperature affects the decomposition of paper?
Yes if it is the right temperature the bacteria and other decomposers will be able to decompose the paper better. If it is colder then the bacteria will slow down. If it is too hot they will die.
Which bacteria can grow in the refrigerator?
It depends entirely on the type of bacteria and the temperature in the fridge.
What will happen to food poisoning bacteria at body heat?
Generally they just go dormant. To remove bacteria, they need to be killed off by heat at a minimum of 63 degrees.
Why must the temperature of the agar be no lower than 45C and no higher than 50C when being poured into the plates?
the bacteria will dentaure and die off
