Answer

I think that all types of microorganism can not live in the type of condition

Answer

But I think that in HOT AND COLD TREATMENT ...there is a sudden change for microorganisms which they cannot face and die

Answer

Hot and Cold Treatment/Pasteurization
Microorganisms can live in almost all types of environments due to their adaptability. However, they are not able to survive hot and cold treatment or pasteurization due to the following reasons:

Heat Treatment
- Heat treatment involves subjecting the microorganisms to high temperatures, which can denature their proteins and enzymes.
- Denaturation of proteins leads to loss of their structure and function, ultimately causing the microorganisms to die.
- High temperatures can also disrupt the cell membranes of microorganisms, leading to leakage of cellular contents and cell death.

Cold Treatment
- Cold treatment involves subjecting the microorganisms to low temperatures, which can slow down their metabolic processes.
- Low temperatures can inhibit the growth and reproduction of microorganisms, eventually leading to their death.
- Cold temperatures can also cause ice crystal formation within the cells, damaging their structure and function.

Pasteurization
- Pasteurization is a process of heating food or liquid to a specific temperature for a set period of time to kill harmful microorganisms.
- The heat treatment during pasteurization destroys the pathogens present in the food or liquid without significantly affecting its taste or nutritional value.
- Pasteurization is commonly used in the food industry to ensure the safety of products such as milk, juice, and canned goods.
In conclusion, hot and cold treatments, as well as pasteurization, are effective methods for killing microorganisms by disrupting their cellular structures and functions. This helps to ensure the safety and quality of various products in different industries.
