Freezing does kill the bacteria because it freezes the cell movement. Bacteria has to maintain in movement to stay alive. Also when it freezes, it shatters easily. This kills the bacteria almost immediately.

Does freezing kill salmonella bacteria?
No, it doesn't kill much of the bacteria at all and the bacteria remaining will grow during defrosting.
What result from Griffith experiment suggested that the cause of pneumonia was not a chemical poison released by the diseases causing bacteria?
The difference between "walking pneumonia" and "true pneumonia".
Are bacteria killed by freezing?
Yes, bacteria can survive freezing temperatures. Freezing isn't a sure-fire way to kill the bacterial population in the food. The only thing freezing will do is halt the multiplication of bacteria however thawing will resume the process.
Will Refrigerating or freezing foods will kill any bacteria present in the food?
true
Is pneumonia caused by a virus or bacteria?
a bacteria. the bacteria that causes pneumonia is called pneumoniae.
Pneumonia is a bacteria or virus?
Pneumonia is an inflammation or infection of the lungs most commonly caused by a bacteria or virus. Pneumonia can also be caused by inhaling vomit or other foreign substances.
What result from Griffiths experiment suggested that the cause of pneumonia wasnt a chemical poison?
To find out, he took a culture of these cells, heated the bacteria to kill them, and injected the heat-killed bacteria into the mice. The Mice survived, suggesting that the cause of pneumonia was not a chemical poison released by the disease-causing bacteria.
Explain how the bacteria in griffith's experiment were transformed?
The harmless living bacteria took in pneumonia-causing DNA(genes) from the heat-killed, pneumonia-causing bacteria, as a result of which the harmless bacteria changed into bacteria that cause pneumonia.
Is excrement safe to eat after freezing?
Freezing bacteria doesn't kill it. It 'slows' it down. When I mean 'slows' it down I mean that by it going to sleep or something. as soon as the bacteria defrosts, it comes back to life.
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.
What is encapsulated pneumonia?
Pneumonia caused by an infection with an encapsulated bacteria.
What results from Griffiths experiment suggested that the cause of pneumonia was not a chemical poison by the disease-causing bacteria?
To find out, he took a culture of these cells, heated the bacteria to kill them, and injected the heat-killed bacteria into the mice.
