Bacteria can and do survive cold conditions. They just don't grow. But it is true that a refrigerator set around 36°F will keep food longer than if it were set at 40°F.
With the help of endospores, or thick-walled structures that help the bacteria survive harsh conditions.
endospores
Endospores are dormant, resistant structures formed by some bacterial species to survive harsh environmental conditions such as extreme temperatures or lack of nutrients. They allow bacteria to remain viable for long periods and then germinate once conditions become favorable again.
There are no microorganisms that can survive all conditions. While some microorganisms (such as extremophiles) can survive in extreme environments like high temperatures, high salinity, or low pH, no single microorganism can survive in absolutely all conditions due to the vast diversity of environments on Earth.
When growing conditions are not right, many bacteria form
Some examples of bacteria that can survive in the refrigerator include Listeria monocytogenes and Yersinia enterocolitica. It is important to practice proper food handling and storage techniques to prevent bacterial growth in refrigerated foods.

they become unable to multiply. unlike humans, all bacteria are different and have varied temperatures at which they function best. just think of food in general--while putting your food in the fridge can limit the growth of bacteria for a short period of time (that's why we put food in the fridge), it will not prevent some bacteria from eventually growing (which is why food spoils even when it is kept in the fridge). even in extremely low temperatures (like the freezer), some bacteria will be able to grow--it all depends on the temperatures at which the bacteria function best.
