Refrigeration Bacteriostatic or Bactericidal
On the principle of refrigeration bacteriostatic or bactericidal
There are ways to store things in the world, and refrigeration is one of them. However, when it comes to bacteria, there are different opinions on whether to inhibit bacteria or sterilize them. There are different opinions. Now it is time to distinguish them in detail.
Bacteria are tiny things, born in the world, and multiply very quickly. Their survival depends on suitable temperature, humidity, and nourishment. Those who are warm are especially serious. When it is at room temperature, the metabolism of bacteria is smooth, and the biochemical path is orderly, so that they can multiply and breed.
The method of refrigeration reduces its temperature, so that it is nearly cold but not frozen. For bacteria, under low temperature, the intracellular biochemical reaction slows down. The metabolism of bacteria depends on enzymes to promote it. Enzymes are specific and live according to temperature. When the temperature is low, the activity of enzymes decreases, the rate of biochemical reactions decreases, and the growth and reproduction of bacteria are blocked. This is a sign of bacteriostatic. For example, grass in the field grows slowly in the case of autumn cold, although it is not extinct, its vitality is stagnant. Bacteria in a refrigerated environment are just like grass in the case of cold, growth slows down, but they die before they die, so it shows the effect of bacteriostatic.
However, some people say that refrigeration can sterilize. In places with extreme cold, there are few bacteria, which seems to be evidence. However, after careful investigation, extreme cold is different from refrigeration. The temperature of refrigeration is not extremely low, but only decreases and is controllable. Although the growth of bacteria is suppressed, it does not reach the state of death. Some cold-resistant bacteria can still survive under refrigeration conditions, and recover when the temperature is suitable. For example, under permafrost, there are occasional archaea, although after a long time of low temperature, in a suitable environment, they can still revive and multiply. Therefore, it is difficult to achieve the effect of sterilization only by refrigeration.
To sum up, the method of refrigeration is mostly bacteriostatic. Although the activity of bacteria is reduced, its reproduction is slowed down, but its vitality is not lost. To sterilize, high temperature, chemical agents and other methods are often required to remove germs and keep things safe. It is appropriate to use refrigeration when it is clear that it is a bacteriostatic policy, and non-sterilization methods are used in food preservation, medical and drug storage, etc., according to its nature.
